Abstract

Branched unsaturated fatty alcohol ether sulfates are claimed which are obtained by: (a) removing the monomer fraction from conventionally dimerized 16-22C unsaturated fatty acids; (b) converting the branched, unsaturated fatty acids to the methyl ester; (c) hydrogenating the ester to the corresponding alcohol with retention of the unsaturation; and (d) conventionally alkoxylating, sulfating and neutralizing the alcohol with retention of the unsaturation.

Description

Field of invention

The invention is in the field of anionic surfactants and relates largely to unseeded saturated fatty alcohol ether sulfates, which are opposed to each other as a result of branches in the hydrocarbon chain distinguish a process through significantly improved properties via linear homologues their production and their use for the production of surface-active agents.

State of the art

Sulphates of unsaturated fatty alcohol ethoxylates, which are essentially produced by ethoxylation, sulphation and subsequent neutralization of the corresponding tallow-based alkenols are obtained, make way raw materials for the production of cosmetic preparations as well as washing, dishwashing and detergents. The beneficial properties of these substances are due to their presence the double bond in the molecule, which at the same time also raises problems because the unge saturated fatty alcohol ether sulfates easily fall prey to autoxidation, which leads to discoloration and un desired chemical changes (e.g. formation of peroxides and hydroperoxides) is.

It is therefore clear that the desire for unsaturated fatty alcohol ether sulfates on the market with verbes serter oxidation stability or suitable substitutes, which have at least equivalent have application properties. As an alternative to unsaturated fatty alcohol ether sulfates however, so far only more or less pure isostearyl alcohol ether sulfates have been available the. To produce them, however, it is first necessary to dimerize oleic acid, the fraction to separate monomeric, branched fatty acids, to harden, to a fractional crystallization to un to separate the resulting liquid, isostearic acid-rich fraction with methanol esterify and then hydrogenate the esters to the alcohols, which then finally to next are converted into the alkoxylates and then into the ether sulfates.

The process outlined above, however, is technically complex and easy due to the two hydrogenation steps uses the isostearyl alcohol ether sulfates to produce substitutes for the unsaturated fatty alcohol ether sulfates can only partially replace. Thus, the task of the present task has been to unge To make saturated fatty alcohol ether sulfates available, which can be improved through improved application technology niche properties, preferably a higher oxidation stability.

Production of fatty alcohols

The dimerization of fatty acids and the recovery of monomer fatty acids from the dimerizates is sufficiently known from the prior art. In this context, reference should be made, for example, to the reviews by A. Behr et al. [Fat Sci. Technol. 93, 340 (1991)] and H. Möhring et al. [ibid. 94, 41 (1992) and 94, 241 (1992)]. The sequence of steps (a) to (d) yields _{branched, largely unsaturated fatty alcohols based on dimerized, preferably monounsaturated C 16} to C ₂₂ fatty acids, i.e. oleic acid, elaidic acid, petroselinic acid, gadoleic acid and erucic acid and mixtures thereof in the iodine number range from 45 to 85. This is undoubtedly completely sufficient for a number of applications, but if fatty substances are required which have a higher content of unsaturated compounds, it is recommended that the monomer fraction obtained in the dimerization is first a fractional crystallization and the resulting liquid phase, if necessary, subjected to the esterification after distillation. The resulting fatty acid and its methyl ester represent a fairly pure isooleic acid or isooleic acid methyl ester, which have an iodine number in the range from 75 to 95. In any case, it is advisable to subject the methyl esters and / or the fatty alcohols to distillation and / or fractional crystallization ("winterization"). The esterification of the fatty acids with methanol takes place according to the processes of the prior art and is used to produce methyl esters, which are comparatively easy to hydrogenate. Instead of the Methyle ster can of course also other lower alkyl esters, such as. B. ethyl, propyl or butyl esters are generated and then hydrogenated, the selection of the alcohol is not critical and is ultimately based on economic criteria and availability. Instead of the methyl or lower alkyl esters, it is in principle also possible to esterify the fatty acids directly, but then special catalysts are required for this purpose which do not form salts with the acids; In addition, the reactor material must be corrosion-proof. The hydrogenation of the unsaturated methyl esters to give the corresponding alcohols can also be carried out in a manner known per se. Corresponding processes and catalysts, in particular those based on copper and zinc, can be found, for example, in the following publications: DE 43 35 781 C1, EP 0 602 108 B1, US 3,193,586 and US 3,729,520 (Hen kel); express reference is made to the content of these documents.

Alkoxylation

The branched, largely unsaturated fatty alcohols obtained previously are then used in an alkoxylated in a known manner, d. H. to the hydroxyl group ethylene oxide, propylene oxide or their Mixtures deposited in random or block distribution. Preferably an average of 1 to 50, in particular 5 to 15 moles of ethylene oxide and / or 1 to 5 moles of propylene oxide are added. The alkoxylation takes place according to the processes of the prior art, that is usually in the presence of alkaline ho homogeneous or heterogeneous catalysts, such as. B. sodium methylate, potassium tert-butoxide or calcined or hydrotalcite hydrophobicized with fatty acids. Accordingly, the alkoxylates can also be a conventionally broad or narrow homolog distribution.

Sulfation and neutralization

The previously prepared fatty alcohol alkoxylates can also be converted into the sulfates in a manner known per se. The sulfating agent can attack both the hydroxyl group and the double bond. However, since the sulfation is about 10 times faster than the sulfonation, i.e. the addition of sulfur trioxide to the double bond, especially at low temperatures in the range of about 30 ° C., (ether) sulfates are predominantly, ie more than 90% by weight obtain. The reaction of the branched, largely unsaturated fatty alcohols, for example with gaseous sulfur trioxide, can be carried out in the manner known for fatty acid lower alkyl esters [J. Falbe (ed.), "Surfactants in consumer products"; Springer Verlag, Berlin-Heidelberg, 1987, p. 61] success conditions, with reactors that operate on the falling film principle are preferred. The sulfur trioxide is diluted with an inert gas, preferably air or nitrogen, and used in the form of a gas mixture containing the sulfating agent in a concentration of 1 to 8, in particular 2 to 5% by volume. The molar ratio of alkoxylate to sulfating agent used is usually 1: 0.95 to 1: 1.8, but preferably 1: 1.0 to 1: 1.6. and in particular 1: 1.3 to 1: 1.5. The sulfation is usually carried out at temperatures of 25 to 90, preferably 35 to 80.degree. Instead of sulfur trioxide, chlorosulfonic acid or amidosulfonic acid can also be used as sulfonating agents. The acid sulfates obtained in the reaction are stirred into aqueous bases, neutralized and adjusted to a pH of 6.5 to 8.5. The neutralization is selected with bases from alkali metal hydroxides such as sodium, potassium and lithium hydroxide, alkaline earth metal oxides and hydroxides such as magnesium oxide, magnesium hydroxide, calcium oxide and calcium hydroxide, ammonia, mono-, di- and tri-C _2-4 alkanolamines , for example mono-, di- and triethanola min and primary, secondary or tertiary C _1-4 -alkylamines carried out group formed. The neutralization bases are preferably used in the form of 5 to 55% by weight aqueous solutions, 25 to 50% by weight aqueous sodium hydroxide solution being preferred. The sulfates obtainable by the process according to the invention are, after neutralization, in the form of aqueous solutions with an active substance content of 20 to 80, preferably 30 to 50% by weight. After neutralization, the sulfates can be bleached in a manner known per se by adding hydrogen peroxide or sodium hypochlorite solution in order to achieve a further color increase which is desired for many applications. Here, based on the solids content in the sulfate solution, 0.2 to 2% by weight of hydrogen peroxide, calculated as a 100% by weight substance, or corresponding amounts of sodium hypochlorite are used. The pH of the solutions can be adjusted using suitable buffers, e.g. B. be kept constant with sodium phosphate or citric acid. To stabilize ge tion against bacterial infestation, a preservation is also recommended, z. B. with formaldehyde solution, p-hydroxybenzoate, sorbic acid or other known preservatives.

Examples example 1

23 kg of Edenor® 935 monomer fatty acid (Henkel KGaA) were esterified with 20 kg of methanol for 2 hours at 240 ° C. and 100 bar. After the water / methanol mixture had been separated off, the same amount of fresh methanol was added and the process was repeated twice. The ester obtained in this way had an acid number of 0.8. The methyl ester was hydrogenated in the fixed bed mode over a Zn — Cr catalyst with retention of the double bond. In this case, 0.5 volume units of methyl ester per hour - based on the total volume of the system - were enforced. After the methanol had been stripped off, the crude alcohol was distilled (3% first run, 90% main run, 6% residue). The resulting alcohol showed a hydroxyl number of 192, a saponification number of 0.9 and an iodine number of 74; the fixed point was 25.8 ° C. 293 g (1 mol) of the isooleyl alcohol thus obtained were placed in a stirred autoclave and dried at 100 ° C. for about 45 minutes. After the addition of 2 g of sodium methylate in the form of a 30% strength by weight methanolic solution as a basic catalyst, the ethoxylation was carried out with 88 g (2 mol) of ethylene oxide at 120 to 160 ° C. and an autogenous pressure of 5 bar. After cooling, the reaction mixture was evacuated in order to remove traces of unreacted ethylene oxide. The isooleyl alcohol + 2EO adduct had the following characteristics: OHN = 146, IZ = 65 : 1.05 sulfated in a falling film reactor at 30 ° C. and a dilution of 5% sulfur trioxide / nitrogen and neutralized with aqueous sodium hydroxide solution immediately after leaving the reactor. To destroy cyclic sulfation products, hydrolysis was carried out at pH 10 for one hour. The analysis of the isooleyl ether sulfate sodium salt gave the following values.

Example 2

Monomer fatty acid was largely freed from straight-chain, saturated fatty acids by crystallization from methanol / water (Emersol process). In this way approx. 20% by weight fatty acid, predominantly palmitic and stearic acid, was separated off. The liquid fatty acid mixture obtained after distilling off the solvent had a titer of 5 ° C. and was first converted into the methyl ester analogously to Example 1 and then hydrogenated to the unsaturated fatty alcohol. This showed a hydroxyl number of 191, a saponification number of 1.7 and an iodine number of 87; the fixed point was 3.8 ° C. 293 g (1 mol) of the isooleyl alcohol thus obtained were placed in a stirred autoclave and dried at 100 ° C. for about 45 minutes. After the addition of 2 g of sodium methylate in the form of a 30% strength by weight methanolic solution as a basic catalyst, the ethoxylation was carried out with 88 g (2 mol) of ethylene oxide at 120 to 160 ° C. and an autogenous pressure of 5 bar. After cooling, the reaction mixture was evacuated in order to remove traces of unreacted ethylene oxide. The isooleyl alcohol + 2EO adduct had the following characteristics: OHN = 146, IZ = 65 : 0.95 sulfated in a falling film reactor at 35 ° C. and a dilution of 5% sulfur trioxide / nitrogen and neutralized immediately after leaving the reactor with aqueous sodium hydroxide solution. To destroy cyclic sulfa treatment products, hydrolysis was carried out for one hour at pH = 10. The analysis of the isooleyl ether sulfate sodium salt gave the following values.
