Definitions
- the invention relates to sucrose-N-alkylasparaginates of the formula (I) according to FIG. 1, their preparation and use.
- Sucrose as a hydrophilic component, is converted with fatty acid derivatives according to common processes to the known sucrose fatty acid esters (FIG. 2), which can be used as industrial auxiliaries and additives due to their amphiphilic properties.
- the known compounds according to FIG. 2 are described as non-toxic, non-irritating to the skin and readily biodegradable.
- esters of sucrose according to FIG. 2 are mainly produced on an industrial scale by means of transesterification processes:
- sucrose is reacted with fatty acid methyl ester R ⁇ COMe in the presence of a basic catalyst in a solvent such as dimethylformamide or dimethyl sulfoxide (JP 04,247,095).
- a solvent such as dimethylformamide or dimethyl sulfoxide (JP 04,247,095).
- the fatty acid ester is dispersed in a solution of the carbohydrate using an emulsifier. The solvent is removed before the actual esterification takes place (EP 0254376).
- the known transesterification processes are very expensive both in terms of their process control and product isolation.
- the reaction parameters pressure and temperature have to be carefully checked and to obtain the sucrose esters it has to be extracted and distilled several times.
- the high reaction temperatures in combination with the long reaction times lead to discoloration of the products, which can only be reversed using complex cleaning processes.
- a further disadvantage of the compounds according to FIG. 2 is that they are used as monoesters. as diesters show surface-active properties, but because of their limited solubility in water they can only be used to a limited extent as surfactants.
- the monoesters dissolve poorly in cold water, while the diesters are only emulsifiable in water.
- EP 0324595 describes “amino-functional compounds as builders / dispersants in cleaning agents” which are obtained by adding amino acids to maleate half-esters of polyols. The latter are obtained by reacting maleic anhydride, in particular with polyvinyl alcohol, also including sucrose. Although the reaction of maleic anhydride with alcohols has been known for a long time, the subsequent reaction with amino acids is problematic since this requires a balanced system of buffers and bases which suppresses the alkaline back-reaction of the maleate half-ester, preferably NaOH / Na2CO3.
- the maleate half ester of sucrose according to Fig. 3 is e.g. as a builder (CO / builder) in detergents (DE 2148279).
- R 8 is a C 8 -C 22 -alkyl or alkenyl radical
- R 9 and Rn inter alia, also hydrogen and Rio can also mean a carboxyl group.
- such “acidic esters” cannot be produced by the multi-stage process described in DE 2739343, because only “basic esters” of sucrose are accessible thereafter, ie completely esterified carboxylates in which the carboxyl group (radical R-
- the object of the present invention was therefore to provide new derivatives of sucrose which are easy to prepare and can be used as surface-active compounds.
- "acid esters" of sucrose have the required properties.
- the present invention therefore relates to sucrose-N-alkylasparaginates of the formula (I)
- R1 independently of one another, identically or differently, a group selected from hydrogen, a compound of the formula (II)
- R is CnH 2 n + ⁇ or C n H2n, where n is an integer from 2-28, preferably from 6-22, especially from 12-18, a compound of the formula (III)
- M + is hydrogen, an alkali metal ion and / or an alkaline earth metal ion, preferably a sodium, potassium, lithium, magnesium, calcium and / or ammonium ion, with the requirement that at least one radical R 1 is a compound of the formula (II) is.
- the “basic esters” in DE 2739343 are described as clearly water-soluble, resinous and little or practically non-foaming.
- the “acid esters” of the formula (I) according to the invention are partially crystalline but amorphous solids with only limited water solubility, with very stable, good foam-forming emulsions are formed. This is particularly surprising because aliphatic esters of carboxylic acids are generally less water-soluble than their salts.
- the present invention therefore provides novel sucrose-N-alkylasparaginates of the formula (I) which can be prepared surprisingly smoothly in high yields by a two-stage one-pot process and which are widely biodegradable, physiologically compatible and surface-active substances can be used.
- the compounds according to the invention are notable for the fact that at least one and up to eight Ri radicals represent a 3-alkylamino-substituted half-ester radical of 1,4-butanedicarboxylic acid or its salts according to formula (II).
- M ® H ⁇
- the compounds according to the invention - as is typical for amino acids - can also be used as internal salts (betaines) with protonation of the Amino function are present.
- M ® is preferably an ion of the alkali and alkaline earth metals such as Na ® , K ® , Li ® , Mg 2+ , Ca 2+ and NH 4 ® , particularly preferably sodium or potassium ions or mixtures thereof.
- Suitable alkylamino radicals NHR 2 come from primary amines (monoalkylamines
- R 2 NH2 of chain lengths C2 to C28 > preferably of commercially available fatty amines with chain lengths of CQ to C22, in particular of C12 to Cis, which are also hydrogenated from more or less wide production cuts, for example from coconut, from palm, Soybean or tallow oil fats are obtained, especially from decyl, dodecyl, tetradecyl, hexadecyl or octadecylamines or from residues derived from coconut, palm, soybean or tallow oil fats. Accordingly, the compounds according to the invention can also carry different radicals.
- coconut fat generally contains a mixture of hexane, octane, decane, lauric, myristic, palmitic, stearic, behen, oil and linoleic acid residues.
- Palm oil generally contains a mixture of myristic, palmitic, stearic, oil and linoleic acid residues.
- Soybean oil contains, inter alia, residues with a carbon chain length of 14, 16, 18, 20 and 22 carbon atoms, usually C 14 unsaturated, C 16 monounsaturated and saturated, C ⁇ monosaturated, triple and triple unsaturated and saturated, C20 monounsaturated and saturated and C 22 is saturated. Taigfett generally contains residues with 14, 16 and 18 carbon atoms.
- radicals R 1 can also be present in sulfated form, the sum of the radicals A, B and C naturally not being able to exceed the number 8.
- Another object of the present invention is a process for the preparation of a sucrose-N-alkylasparaginate of formula (I), wherein in a first step sucrose is acylated with maleic acid or a derivative of maleic acid, and in a second step one to eight molar equivalents of amine of the formula R 2 NH 2 with R 2 equal to C n H 2 n + ⁇ , where n is an integer from 2-28, preferably 6-22, especially 12-18 the maleate sucrose formed in the first step is added.
- the process according to the invention consists in the acylation of the sucrose with preferably maleic anhydride (MSA) and the subsequent addition of fatty amines to the CC double bond of the intermediate maleat sucrose, preferably without isolation or purification of the intermediate.
- Another suitable acylating agent is maleic acid chloride.
- the fatty acid residue is not introduced directly by acylation of the OH groups of the sucrose, but indirectly via the addition of the fatty amines to the preferably non-isolated intermediate. This creates an N-alkylated aspartic acid, which acts as a linker group for the lipophilic alkyl radical. Both substeps are largely stoichiometric in terms of additions without the formation of stoichiometric amounts of salt as by-products.
- the acylation is carried out in the presence of a catalyst, preferably in the presence of a basic metal salt, in particular a carbonate, bicarbonate, acetate and / or formate.
- a basic metal salt in particular a carbonate, bicarbonate, acetate and / or formate.
- a basic metal salt in particular a carbonate, bicarbonate, acetate and / or formate.
- a basic metal salt acts as a catalyst in the acylation with MSA and for the neutralization of the carboxylate formed.
- By-products are, depending on the metal salt, the easily separable acetic acid or carbon dioxide.
- the formation of the carboxylate salt advantageously prevents the consumption of a salt-bound fatty amine equivalent, which would then no longer be available for the subsequent addition to the CC double bond.
- the carboxylate group formed in the first step additionally improves the hydrophilic properties and the water solubility of the surface-active substances. Surprisingly, the process manages completely without addition of aqueous bases and buffer systems, for example as described in the application EP 0324595, which is therefore particularly advantageous.
- the sucrose-N-alkylaspartate is sulfonated in a further step, preferably up to two radicals R 1 using one of the methods familiar to the person skilled in the art Functionalization of hydroxyl and amino groups can be sulfonated.
- the reaction products are reacted in the same reaction vessel or after separating off the intermediates with the calculated amount of a sulfonating reagent, if appropriate after adding an inert solvent such as dichloromethane, tetrahydrofuran or dioxane.
- Suitable sulfonating reagents are e.g. B. S ⁇ 3 ) CISO3H, DMF-SO3 and / or pyridine-S ⁇ 3.
- the advantages of the process according to the invention compared to the known production processes are the high reactivity of the maleic anhydride and the nucleophilic attack of the fatty amine on the electrophilic CC double bond, as a result of which further purification steps, expensive auxiliary bases or auxiliary reagents, such as catalysts, can be dispensed with for this reaction step .
- the process also makes it possible to provide a large number of differently substituted compounds of the formula (I) with tailored application properties and areas of use.
- the yields in the two-stage one-pot process are over 90%.
- Sucrose and the correspondingly calculated amount of, for example, maleic anhydride and, for example, an equivalent amount of a basic metal salt (MX), such as, for example, sodium hydrogen carbonate, sodium carbonate, sodium acetate, sodium formate, lithium acetate or potassium acetate, preferably sodium hydrogen carbonate, sodium carbonate or sodium acetate, are in bulk or in a suitable solvent, for example in N, N-dimethylformamide (DMF), N, N-dimethylacetamide (DMA), dioxane, N-methylpyrrolidone (NMP), DMSO, tetrahydrofuran (THF) or in mixtures of these solvents, preferably in N , N-dimethylformamide, N-methylpyrrolidone, DMSO, dioxane or in mixtures of these solvents, at temperatures from 20 ° C to the boiling point of the solvent or solvent mixture in question, preferably at temperatures in the range from approximately 20 to approximately 140 ° C., in particular at temperatures
- the reaction is complete after the sucrose has been completely consumed, which is easily detectable by thin layer chromatography. Then the amount of the relevant alkylamine R 2 NH2 or the alkylamine mixture calculated in accordance with the desired DS is added and in the same reaction vessel at temperatures from about 0 ° C. to the boiling point of the solvent or the solvent mixture in question, preferably at temperatures of about 20 to about 60 ° C. until the reaction is complete after analysis by thin layer chromatography.
- the end product partially precipitated as a colorless solid during the reaction, which can be filtered off, washed and dried.
- the main amount of the solvents used is preferably distilled off and the product is isolated by stirring in a low-boiling solvent.
- the product can also be precipitated from the reaction solution by adding the appropriate amount of solvent.
- Suitable solvents for the stirring and precipitation processes are ethyl acetate, hexane, methyl isobutyl ketone, acetone and the like. After thorough vacuum drying, the solid end product is obtained as a colorless, odorless powder.
- the negative counter ion used has an effect, for example, on the surfactant properties of the compound according to the invention. By the appropriate selection of the counter ion, for example a paraffin sulfonates, tailor-made thickeners can be produced in formulations for shampoos and other cosmetic cleaning agents as well as for liquid surfactant systems.
- the products obtained are in the same reaction vessel or after separation of the intermediates with the appropriate amount of the sulfonating reagent, preferably up to 2 molar equivalents of the sulfonating reagent, if appropriate after adding an inert solvent such as, for example Dichloromethane, tetrahydrofuran or dioxane.
- Preferred sulfonating reagents are e.g. B. SO3 CISO3H, DMF-SO3 or pyridine-S ⁇ 3.
- the compounds of the formula (I) obtained by the process according to the invention are characterized by means of analytical and spectroscopic methods such as TLC, H NMR and mass spectroscopy and elemental analysis.
- the DS of the products can be determined by means of the proton ratio (integration of the ' ⁇ NMR signals) and by means of elemental analysis.
- alkylamine R 2 NH2 to the sucrose maleates or to mixtures of intermediates, which can contain up to 8 residues R 1 , generally takes place stoichiometrically until the maleate-CC double bond is completely reacted with a certain amine RI NH2.
- the amine R ⁇ NH2 can also be used substoichiometrically while maintaining unsaturated maleate substructures, for example in order to achieve a certain water solubility of the products.
- a mixture of several different alkylamines can also be used. Accordingly, the compounds according to the invention can also carry different radicals.
- the ratio of hydrophilicity to hydrophobicity which determines the surface-active properties of the compounds according to the invention, is adjusted via the structure of the alkyl substituents R 2 and their degree of substitution (DS).
- the DS can be adjusted via the molar ratio of alkylamine R 2 NH2 to sucrose.
- the water solubility of the compounds according to the invention can optionally also be adjusted via additional sulfonate groups, in that a higher number of N-alkyl aspartate residues can be compensated for by preferably up to two sulfonate groups.
- the compounds according to the invention have a total of up to eight radicals R 1 , the DS being between 1 and 8. As the DS increases, the lipophilicity of the compounds increases and their water solubility decreases accordingly. At the same time, this effect can be compensated for by the carboxylate or sulfonate groups introduced. As already explained, the amphoteric character and the water solubility of the surface-active substances can be modulated in a simple manner, which is important for the intended areas of use. For cosmetic applications, for example in shampoos or bath additives, but also in household cleaning agents, such as in dishwashing detergents, good foaming power and good foam stability are important.
- ampho- tere character of the compounds can be expected a special skin tolerance and skin protection effect, since a favorable interaction with the collagen of the skin can occur.
- the hydrophilic carboxylate groups of the asparagine substructure or, if appropriate, additional sulfonate groups ensure good washability from the skin, which is particularly important for body cleansing.
- the DS is therefore preferably approximately 1-3, in particular ⁇ 3, and for low-calorie fat substitutes for foods, preferably approximately> 3, in particular approximately 4-8.
- melting points and taste sensations can be controlled via the composition of the R 2 residues and the DS value: Only those fatty substances with a melting point above body temperature and which are not liquid at room temperature give a pleasant taste sensation.
- a coordinated taste sensation for example for a substitute for cocoa butter, can be achieved by a corresponding mixture of fatty amines of different chain lengths, by C-12 (lauryl-), C-16 (palmityl-), C-10 (caprinyl-), C-14 (Myristyl) and C-18 (stearyl) amines can be used in coordinated proportions.

- surfactants can be influenced by the action of these surface-active substances in their foaming ability by promoting the rising and bursting of the gas bubbles (defoaming).
- foam control agents are used in particular in dishwashing detergents and in many technical processes such as paper and sugar production.
- the low toxicity and biocompatibility known from other sugar residues and from biosurfactants means that the compounds according to the invention also have similarly favorable properties.
