The method for preparing polyhydroxy fatty acid amide is that this specialty is known.General, they can make by the following method: in reductive amination process, alkylamine and reducing sugar reaction, form the corresponding N-alkyl polyhydroxy amine, then, in the condensation amidation step, N-alkyl polyhydroxy amine and aliphatic ester or triglyceride level reaction, form the N-alkyl, N-polyhydroxy fatty acid amide product.The method for compositions that preparation contains polyhydroxy fatty acid amide is known, for example, and Thomas Hedley ﹠amp; Co., Ltd. british patent specification 809,060(1959.2.18 openly), the U.S.P.2 of E.R.Wilson, 965,576(1960.12.20), the U.S.P.2 of Anthony M.Schwartz, 703,798(1955.3.8) and the U.S.P.1 of Piggott, 985,424(1934.12.25), these documents at this as a reference.

At preparation N-alkyl or N-hydroxyalkyl, in a kind of method of N-desoxy sugar alcohol radical fatty acid amide, sugar alcohol base component in this acid amides is obtained by glucose, this N-alkyl or N-hydroxyalkyl functional group are the N-methyl, the N-ethyl, the N-propyl group, the N-butyl, N-hydroxyethyl or N-hydroxypropyl, product makes by N-alkyl in the presence of catalyzer or N-hydroxyalkyl glycosamine and fatty ester reaction, said fatty ester is selected from fatty methyl esters, fat ethyl ester and fat triglyceride, said catalyzer is selected from the tricresyl phosphate lithium, tertiary sodium phosphate, Tripotassium phosphate, tetrasodium pyrophosphate, pentapotassium tripolyphosphate, lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide, Quilonum Retard, yellow soda ash, salt of wormwood, disodium tartrate, the Tartaric acid dipotassium, Tartaric acid sodium potassium, trisodium citrate, citric acid tri potassium, alkaline sodium silicate, alkaline potassium silicate, alkaline sodium aluminosilicate and alkaline potassium aluminosilicate and composition thereof.Molar weight with N-alkyl or N-hydroxyalkyl glycosamine is a benchmark, and the amount of catalyzer is preferably the about 50 moles of % of about 0.5 mole of %-, the about 10 moles of % of even more preferably about 2.0 moles of %-.Generally be preferably in about 138 ℃-170 ℃ reactions about 20-90 minute.When in reaction mixture, using triglyceride level as the fatty ester source, weight with total reaction mixture is benchmark, the most handy about 1-10%(weight) consisting of phase-transferring agent reacts, said consisting of phase-transferring agent is selected from the many ethoxylates of saturated fatty alcohol, alkyl polyglucoside, straight chain glucamide tensio-active agent and composition thereof.

This method preferably is performed as follows:

(a) the preheating fatty ester is to 138-170 ℃;

(b) be added to N-alkyl or N-hydroxyalkyl glycosamine in the fatty acid ester of preheating and be mixed into required degree, form two-phase liquid/liquid mixture;

(c) catalyst mix in reaction mixture;

(d) in the reaction times of regulation, stir.

When if aliphatic ester is triglyceride level, by the weight of reactant, preferably also pregenerated straight chain N-alkyl/N-hydroxyalkyl of about 2%-20%, N-straight chain glucosyl fatty acid amide product is added in the reaction mixture, as consisting of phase-transferring agent, activate this reaction like this, therefore increase speed of response.Experimental section below provides detailed test method.

Here used poly-hydroxy " lipid acid " acid amides is also beneficial to the washing composition makers-up, can be whole or main obtain them by natural, reproducible, non-petrochemical materials, they are degradable, they also show hypotoxicity to hydrocoles.

Should be realized that, except the polyhydroxy fatty acid amide of formula I, produce their used methods and generally also can produce a certain amount of nonvolatile by product, for example esteramides and ring-type polyhydroxy fatty acid amide.The amount of these by products will be along with specific reactant and reaction conditions and is changed.At this point, the polyhydroxy fatty acid amide that preferably merges in the detergent composition will provide with such form, that is, it is about 10% that the amount of ring-type polyhydroxy fatty acid amide contained in the composition of the hydroxyl fatty acid amide that is added in the washing composition is less than, and preferably is less than 4%.Above-mentioned preferable methods also is favourable, because they can produce quite few by product, comprises the by product that cyclic amide is such.

We think that the technology that magnesium is joined in the composition of the present invention is not crucial, and can finish with several different methods.

Therefore, independent anion surfactant can make with the form of the aqueous solution of basic metal or ammonium salt, and itself and hydrotropic agent mix then, and thereafter, magnesium can be with water-soluble salt, and for example the form of muriate or vitriol is introduced.Then, before adjusting PH and viscosity, can add any a spot of component.The advantage of this method is to use conventional technology and equipment, and does not cause introducing other muriate and sulfate ion, and these ions can increase freezing point temperature (in this temperature, the inorganic salt in the liquid precipitate with crystallized form).

If anion surfactant is an acid, so, this acid that can neutralize by the slurries that are used in magnesium oxide in the water or magnesium hydroxide adds.This method avoids adding muriate and sulfate ion.Then neutral surfactant salt and hydrotropic agent are added in the final blending jar, and before adjusting PH, add any optional component.

The third method, and be that most preferred method is form adding anion sulfate or the sulfosalt surfactant with magnesium sulfate salt.When adding the method for magnesium with this, can be with one of additive method given here, or with this professional those of skill in the art's known method, add required magnesium with the anion surfactant of molar excess.

The thickening material that is used for preferred compositions of the present invention is a high molecular polycarboxylic acid ester polymer thickening material.It is about 500 that the meaning of " high molecular " is meant, 000-5, and 000,000, preferred about 750,000-4,000,000.

The polycarboxylic acid ester polymer can be a carboxyvinyl polymer.These compounds are at U.S.P.2, and open in 798,053, this article is classified reference as at this.The method for preparing carboxyvinyl polymer is also open in the document of Brown, and it also classifies reference as.

Carboxyvinyl polymer is a kind of multipolymer that contains the monomer mixture of monomer ethylenically unsaturated carboxylic acids, its amount is the about 0.1-10% of polyether monomer gross weight of polyvalent alcohol, its polyvalent alcohol contains at least 4 carbon atoms, at least be connected with 3 hydroxyls thereon, each molecule of this polyethers contains more than 1 thiazolinyl.If necessary, in this monomer mixture, can have other monoene monomeric substances, even it accounts for main ratio.Carboxyvinyl polymer is to be insoluble to basically in the organic hydrocarbon of evaporating property, and its be exposed in the air be the size stable.

The preferred polyhydric alcohols that is used to prepare carboxyvinyl polymer comprises and is selected from the polyvalent alcohol that carbonyl wherein changes into oligose, its reductive derivative (wherein carbonyl is converted to alcohol radical) and the tetramethylolmethane of alcohol radical; More preferably oligose, most preferably sucrose.The hydroxyl groups allyl etherization that preferably is modified, each polyvalent alcohol molecule of this polyvalent alcohol has two allyl group ethers at least.When polyvalent alcohol is sucrose, best each sucrose molecules of this sucrose 5 allyl group ethers of having an appointment at least.Preferably the content of the polyethers of polyvalent alcohol is total monomeric about 0.1%-4%, is more preferably about 0.2%-2.5%.

Here the preferred monomer alkene unsaturated carboxylic acid that is used to produce carboxyvinyl polymer used herein comprises monomer, polymerisable, the unsaturated lower alphatic carboxylic acid of alpha-beta monoene; The monomer monoene vinylformic acid that more preferably structure is following:

Wherein R is the substituting group that is selected from hydrogen and low alkyl group; Vinylformic acid most preferably.

The molecular weight of carboxyvinyl polymer that is used for preparation of the present invention is at least about 750,000.Preferably molecular weight is at least about 1,250,000 highly cross-linked carboxyvinyl polymer.Molecular weight is at least about 3,000,000, can be that less highly cross-linked carboxyvinyl polymer also is preferred.

Various carboxyvinyl polymers can be by B.F.Goodrich Company, New York, and N.Y. has bought, and its trade(brand)name is that the carboxyvinyl polymer that Carbopol. is used for preparation of the present invention comprises that molecular weight is about 750,000 Carbopol 910; Preferably molecular weight is about Carbopol of 1,250,000 941, and more preferably molecular weight is respectively about Carbopol 934 and 940 of 3,000,000 and 4,000,000.

Carbopol934 is about 3,000,000 the carboxyvinyl polymer of very slight crosslinked molecular weight.By the agency of each molecule sucrose of a kind of and about 1% average about 5.8 allylic many crosslinked high-molecular weight polyacrylic acid of rare propyl group sucrose are arranged.

The polycarboxylate polymkeric substance of the present invention that is used in addition is Sokolan PHC-25 ^R, a kind of polyacrylic acid that can buy by BASF Corp., and GantrezR, a kind of poly-(methylvinylether/toxilic acid) multipolymer that can buy by GAF Corp..

Preferred polycarboxylate polymkeric substance of the present invention be non-linear, water is dispersible, about 750 with the crosslinked molecular weight of polyene-based polyethers, 000-4,000,000 polyacrylic acid.

The most preferred example of these polycarboxylate polymer viscosifiers is the Carbopol 600 serial resins that can have been bought by B.F.Goodrich.Particularly preferably be Carbopol 616 and 617.It is believed that these resins are that more highly cross-linked and molecular weight is about 1,000 than 900 serial resins, 000-4,000,000 resin.Here the polycarboxylate mixture of polymers of Jie Shaoing also can be used for the present invention.Particularly preferably be the mixture of Carbopol 616 and 617 serial resins.

The polycarboxylate polymer viscosifier preferably uses with essentially no clay thickening material.In fact, find,, with regard to phase instability, generate the product that not too meets the requirements if polycarboxylate polymkeric substance of the present invention and clay one are used from the composition of the present invention.In other words, in composition of the present invention the most handy polycarboxylate polymkeric substance substitute for clay as thickening/stablizer.

The polycarboxylate polymkeric substance also makes usually said " bottle hangs " to reduce.This term refers to that incompetence distributes all to wash dishwashing and wash product from its container.Do not want to be limited by theory, we think that thickening combination of the present invention has this advantage, because the power of the force of cohesion specific viscosity of said composition to the wall of container wants big many.Use the clay thickener system, it is the easiest product of having bought, and under certain conditions, it may be important problem that bottle hangs.

Do not want to be limited by theory, we think that also the polycarboxylate polymer viscosifier of long chain molecule helps solid suspension in the detergent composition of thickening of the present invention, and help this matrix development.When said composition is mixed tempestuously, to shear owing to produce multiple like this, this polymkeric substance is littler than the susceptibility that clay thickening material wrecks.

As the thickening material of this multi-carboxy acid copolymer as composition of the present invention, its general amount is about 0.1%-10%, and preferably about 0.2%-2%(is heavy).

The another kind of method of the polyhydroxy fatty acid amide that preparation the present invention is used is as follows.Use contains 84.87g fatty acid methyl ester (source: Procter ﹠amp; Gamble methyl esters CE1270), 75g N-methyl D-glycosamine (source: Aldrich Chemical Company M4700-0) the 1.04g sodium methylate (source: Aldrich Chemical Company 16,499-2) and the reaction mixture of the methyl alcohol of 68.51g.Reaction vessel comprises the standard circumfluence device that drying tube, condenser and stirring rod are housed.In this method, the N-methylglucosamine at argon gas with under stirring with methanol mixed, in fine mixing (stirring rod; Heating) begins heating under the situation.After 15-20 minute, when solution reaches temperature required, add ester and sodium methoxide catalyst.Sampling regularly is so that monitor reaction process, but attention solution in the time of 63.5 minutes is transparent fully.Conclude that at this moment in fact reaction finish nearly.Made reaction mixture refluxed 4 hours.After removing methyl alcohol, the heavy 156.16g of the crude product of recovery.Vacuum-drying and refining after, obtain refined products 106.92g altogether.But the percentage yield is not according to this basic calculation, because the sampling of entire reaction course rule makes total percentage yield value lose meaning.Reaction can reach 6 hours to obtain product under 80% and 90% reactant concn, have only few by product to form.

Not to want to limit the present invention below, but simply further specify the admissible technology aspect other of when preparing various detergent composition makers-up with polyhydroxy fatty acid amide.

People can be easy to recognize that under the condition of high alkalinity or peracidity, polyhydroxy fatty acid amide is owing to their amido linkage, and it just has certain unstable.Although can allow certain decomposition, preferably these materials are not higher than approximately 11, preferred 10 at pH value, are not lower than about 3 times unsuitable time expands at PH yet.The finished product PH(liquid) generally be 7.0-9.0.

In the process of preparation polyhydroxy fatty acid amide, generally need be to the alkaline catalysts of small part neutralization in order to the formation amido linkage.Although acid arbitrarily can be used for this purpose, the makers-up of washing composition will recognize, with a kind of that other purposes can be provided and be that desired anionic acid is very simple and thing very easily in the finished product detergent composition.For example, citric acid can be used for the neutral purpose, and the citrate ion of formation (about 1%) allows to reside in about 40% polyhydroxy fatty acid amide slurry, and is pumped into the preparation process of the back of whole production of detergents process.Acid material such as oxo disuccinate, nitrilotriacetic acid(NTA) salt, edetate, tartrate/succinate etc. can use equally.

By coconut alkyl fatty acid (main C ₁₂-C ₁₄) polyhydroxy fatty acid amide that obtains is than their Tallow, beef alkyl (main C ₁₆-C ₁₈) counterpart solubilized more.Therefore, C ₁₂-C ₁₄Material is fitted in the liquid composition a little easily, and easier being dissolved in the cold water laundry bath.But, this C ₁₆-C ₁₈Material also is of great use, particularly is heated under the environment of hot wash water in usefulness.In fact, C ₁₆-C ₁₈Material is than their C ₁₂-C ₁₄Counterpart may be better detergent surfactant.Therefore, when selecting special polyhydroxy fatty acid amide to be used in the given preparaton, the makers-up may wish the relation between easy preparation of balance and the performance.

People also will recognize passes through to have saturated and/or the side chain point can increase polyhydroxy fatty acid amide solubleness at fatty acid part.So, as the positive alkyl counterpart easier dissolving of the material by oleic acid and Unimac 5680 deutero-polyhydroxy fatty acid amide than them.

Equally, the solubleness of the polyhydroxy fatty acid amide that makes by two saccharidess, three saccharidess etc. big than them usually by single saccharides deutero-counterpart.When being mixed with liquid composition, this bigger solubleness can have special help.In addition, when being used as washing composition with conventional alkylbenzene sulfonate (" LAS ") tensio-active agent, wherein poly-hydroxy is good especially by this polyhydroxy fatty acid amide Presentation Function of maltose deutero-.Though do not want to be limited by theory, seemingly LAS with by the advanced glycation thing, the mixture of the polyhydroxy fatty acid amide that obtains as maltose causes in water-bearing media significantly and unexpected reduction interfacial tension, therefore, has improved final scourability.(method that is prepared polyhydroxy fatty acid amide by maltose is narrated in the back).

Not only can prepare polyhydroxy fatty acid amide by the sugar of purifying.And can be by hydrolyzed starch, for example W-Gum, potato starch or any other cheap contain the makers-up needed single, two, or the like the starch preparation that obtains by plant of saccharides.From the viewpoint of economy, this is a particularly important.So " high glucose " maize treacle, " high malt sugar " maize treacle etc. can economic easily uses.Taking off xyloid hydrocellulose slurries also can provide the raw material sources of polyhydroxy fatty acid amide.

As mentioned above, the polyhydroxy fatty acid amide that is obtained by advanced glycation thing such as maltose, lactose or the like is than their the easier dissolving of glucose counterpart.In addition, as if more can help to dissolve their seldom dissolved counterpart by the dissolved polyhydroxy fatty acid amide, to change solubleness.Therefore, the makers-up can select to use the raw material that contains high glucose maize treacle, also can select to contain the syrup of a small amount of maltose (for example 1% or more).General, the polyhydroxy fatty acid amide that the mixture of the polyhydrony fatty acid of formation obtains than " pure " glucose will present better solubility performance in the temperature of broad and concentration range.Therefore, use the mixture rather than the pure sugared reactant of sugar, except advantage economically, by the polyhydroxy fatty acid amide of blended sugar preparation about performance and/or can obtain clearly benefit easily aspect the preparation.But, in some cases, in lipid acid maltose amide content above about 25% o'clock, can see, being lost in of grease removal performance (washing dish) aspect surpasses at 33% o'clock, sugar aspect lathering property, have loss (said percentage ratio be the polyhydroxy fatty acid amide that obtains of maltose acid amides with mixture in the percentage ratio of the polyhydroxy fatty acid amide comparison that obtains of glucose).According to the chain length of fatty acid part, this may change slightly.In addition, usually, select to use the makers-up of such mixture can find to select to contain single saccharides (for example glucose) with two or the ratio of higher saccharides (as maltose) be about 4: 1-99: the superiority of 1 polyhydroxy fatty acid amide mixture.

Preferably preparing the acyclic polyhydroxy fatty acid amide by fatty ester and N-alkyl polyols can be in alcoholic solvent, at about 30-90 ℃, carries out under preferred 50-80 ℃.Now definite, for, the makers-up of liquid washing agent for example, 1, implementing such method in the 2-propylene glycol solvent may be very easily, because this diol solvent did not need to remove from reaction product fully before the finished product detergent formulations uses.Equally, for for example solid, generally be the makers-up of granular detergent composition, can find at 30-90 ℃, containing the alcohol of ethoxylation, for example (EO-3-8) C of ethoxylation ₁₂-C ₁₄Implementing this method in the solvent of alcohol is very easily, and such alcohol can be with commodity NEODOL23 EO6.5(Shell) bought.When with such ethoxylate, preferably they do not contain the alcohol of the not ethoxylation of obvious amount, and most preferably they do not contain the alcohol of the monosubstituted ethoxyization of obvious amount.(being appointed as " T ").

Do not constitute a part of the present invention although prepare the method for polyhydroxy fatty acid amide, the makers-up also can pay attention to the method for other following synthesis of polyhydroxy fatty acid amides.

Usually, the technical scale reaction sequence for preparing preferred acyclic polyhydroxy fatty acid amide will comprise: the first step, by forming the adducts of N-alkylamine and sugar, and subsequently in the presence of a kind of catalyzer with hydrogen reaction, prepare N-alkyl polyhydroxy sulfonamide derivatives by required sugar or sugared mixture; Then second step, above-mentioned many azanols and preferred fatty ester reaction form amido linkage.Though can prepare the used many azanols of various N-alkyl in the reaction of second step with various prior art disclosed methods, following method is very easily, and can utilize economic syrup to make raw material.Recognize, when with such syrup source, obtain best result, preparation person should select light colour very or preferably near the syrup of colourless (" water-white ").

Syrup by plant derivation prepares the N-alkyl

Many azanols

I. below the formation adducts is a kind of standard method, wherein, add the nail (unit of length) color less than about 55% glucose solution (maize treacle-Yue 231g glucose-Yue 1.28 moles) of about 420g of 1 and about 50% moisture methylamine (59.5g methylamine, the 1.92 moles) solution reaction of about 119g.This methylamine (MMA) solution N ₂Purge also protection, be cooled to about 10 ℃ or lower.Under about 10-20 ℃ temperature, maize treacle N ₂Purge and protection.The following maize treacle of temperature of reaction slowly is added in the MMA solution shown in specified.In specified about several minutes, measure and add the nail (unit of length) color.

50????4????6????10????-????-????-

By above-mentioned data as can be seen, when temperature rise to about during more than 30 ℃ and at 50 ℃, adducts to add the nail (unit of length) color very bad, the nail (unit of length) color that adds of adducts is lower than for 7 only about 30 minutes of time.To long reaction, and/or the hold-time, temperature should be lower than about 20 ℃.For the glycosamine of good color, add the nail (unit of length) color and should be lower than approximately 7, be preferably lower than about 4.

When people prepare adducts with lesser temps, by using the amine of higher rate: sugar, reaching the adducts concentration time in a basic balance can shorten.Amine with 1.5: 1 mol ratios being mentioned: sugar under about 30 ℃ temperature of reaction, reached balance in about 2 hours.1.2: 1 mol ratios, under same condition, the time was at least about 3 hours.For good color, select amine: sugared ratio of mixture, temperature of reaction and reaction times are to reach equilibrium conversion basically, for example greater than about 90%, be preferably greater than about 95%, most preferably greater than about 99%(by sugar), the color of adducts is less than about 7, preferably less than about 4, most preferably less than about 1.

With above-mentioned method, be lower than about 20 ℃ temperature of reaction, with there being specified difference to add the maize treacle of nail (unit of length) color, MMA adducts color (reaching back in a basic balance at least about 2 hours) is as shown in the table.

Maize treacle 111 1+ 00 0+

Adducts 3 4/5 7/8 7/8 121

By above data as can be seen, for uniform the acceptable adducts arranged, initial glycogen material must be very near colourless.When the nail (unit of length) color that adds of sugar is about 1 the time, adducts can be accepted sometimes, can not accept sometimes.When adding the nail (unit of length) color greater than 1 the time, the adducts of formation is unacceptable.The initial color of sugar is good more, and the color of adducts is good more.

II. H-H reaction is above-mentioned, adds the nail (unit of length) color and be 1 or less than 1 adducts, hydrogenation according to the methods below.

At about 20 ℃, the adducts of about 539g in water and about 23.1g United Catalyst G49B Ni catalyzer are added in the 1 liter autoclave, and use 200psig H ₂Purge twice.H ₂Pressure is raised to about 1400psi, and temperature is raised to about 50 ℃.Pressure is raised to about 1600psig then, temperature be maintained at about 50-55 ℃ about 3 hours.At this moment, product about 95% is by hydrogenation.Then temperature be raised to about 85 ℃ about 30 minutes, and reaction mixture poured out, filter out catalyzer.Evaporation remove anhydrate and MMA after, product is about 95%N-methylglucosamine white powder.

Repeat aforesaid method with about 23.1g Raney nickel catalyst and following variation.Catalyst wash 3 times, the 200psig H of the catalyzer in reactor and the reactor ₂Purge 2 times, at 1600psig H ₂Pressurized reactor 2 hours bled off pressure in the time of 1 hour, again reactor was pressurized to 1600psig.Then adducts is pumped into reactor 200psig and 20 ℃, uses 200psig H ₂Purge etc., as mentioned above.

In each case, the product of generation is greater than about 95%N-methylglucosamine, and less than about 10ppm, the color of solution is less than adding nail (unit of length) 2 approximately in glycosamine Ni content.

In the exposure duration of about 140 ℃ of weak points, this phase N-methylglucosamine is a colour stable.

It is very important that the good adducts of the color that low sugar content (be less than about 5%, preferably be less than about 1%) becomes reconciled (＜about 7, preferred＜about 4, best＜about 1 adds nail (unit of length)) is arranged.

In another reaction, initially about 50% methylamine in water with about 159g prepares adducts, and it is to use N at about 10-20 ℃ ₂Purge and protection.Use N at about 50 ℃ of about 70% maize treacle (near water white) about 330g ₂The degassing, and under being lower than about 20 ℃ temperature, slowly be added in the methylamine solution.Mixed this solution about 30 minutes, and obtained about 95% adducts, it is very lurid solution.

At about 20 ℃, the adducts of about 190g in water and about 9g United Catalyst G49B Ni catalyzer are added to 200ml, in the autoclave, and use H ₂Purge 3 times.H ₂Voltage rise is to about 200psig, and temperature is raised to about 50 ℃.Pressure is raised to 250psi, temperature be maintained at about 50-55 ℃ about 3 hours.Then, this moment hydrogenation about 95% product be warmed up to about 85 ℃ about 30 minutes, remove anhydrate and evaporate after, product is about 95%N-methylglucosamine, white powder.

Work as H ₂Pressure minimizes in order to make the Ni content in the glycosamine during less than about 1000psig, and it is very important at least that the contact between adducts and the catalyzer reduces to.Be lower than 10ppm in above the reaction and compare, in this reaction, Ni content is about 100ppm in the N-methylglucosamine.

Below and H ₂Reaction test, in order to the directly relatively effect of temperature of reaction.

Use the 200ml autoclave reactor, be similar to above-mentioned general method and prepare adducts by following, and carry out hydrogenation reaction at various temperatures.

By mixing about 55% glucose (maize treacle) solution (231g glucose of about 420g; 1.28 the 50% methylamine (59.5gMMA of (this solution is to use the 99DE maize treacle of CarGill to prepare, and the color of this solution is less than adding nail (unit of length) 1) and about 119g mole); 1.92 mole) (from Air Products) preparation is used to prepare the adducts of glycosamine.
