Definitions

  • the application relates to a process for the preparation of fatty acid polyglycol ester sulfates by sulfating fatty acid polyglycol esters and subsequent neutralization, and the use thereof of foam boosters especially for nonionic surfactant mixtures.
  • Fatty acid polyethylene glycol esters in particular low ethoxylated fatty acids such as fatty acid + 1 E0 adducts, have been described in the literature for some time as an interesting precursor for the synthesis of ether sulfate surfactants with an isethionate-like structure. Initially, however, it was already difficult to produce the fatty acid polyethylene glycol esters to be used as starting compounds in satisfactory selectivities. In addition to the undesirable proportion of higher ethoxylated homologues, significant amounts of polyethylene glycol and diesters were also formed by the older processes known to date.
  • the object of the present invention was to provide an improved process for the sulfation of especially low alkoxylated fatty acids, which can be used on an industrial scale to supply fatty acid polyglycol ester sulfates without further work-up.
  • the present invention relates to a process for the preparation of fatty acid polyglycol ester sulfates of the formula (I),
  • R 1 CO is a linear or branched, aliphatic, saturated and / or unsaturated acyl radical having 6 to 22 carbon atoms
  • AO is CH2CH2O, CHCH3CH2O and / or CH2CHCH3O
  • n is a number from 0.5 to 5
  • M is a cation , by sulfation of fatty acid polyglycol esters and subsequent neutralization, which is characterized in that the entire neutralization process is carried out at a pH of 5 to 9.
  • R 1 CO is a linear or branched, aliphatic, saturated and / or unsaturated acyl radical having 6 to 22 carbon atoms
  • AO is CH2CH2O, CHCH3CH2O and / or CH2CHCH3O
  • n is a number from 0.5 to 5.
  • the esters can be prepared by known methods of preparative organic chemistry, for example by basic homogeneously catalyzed addition of ethylene oxide and / or propylene oxide to fatty acids.
  • Fatty acids are to be understood as aliphatic carboxylic acids of the formula R 1 COOH, in which R 1 CO is an aliphatic, linear or branched acyl radical having 6 to 22, preferably 12 to 18 carbon atoms and 0 and / or 1, 2 or 3 double bonds.
  • Typical examples are, ristin Textre caproic acid caprylic acid 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristyl, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petrochemical Selin acid, linoleic acid, linolenic acid, elaeostearic acid, arachidic acid, Gadoieinklare, behenic acid and erucic acid and their technical mixtures, which are obtained, for example, in the pressure splitting of natural fats and oils, in the reduction of aldehydes from Roelen's oxosynthesis or as a monomer fraction in the dimerization of unsaturated fatty acids.
  • R 1 CO in formula (I) or (II) is preferably an acyl radical having 12 to 18 carbon atoms.
  • Suitable basic catalysts for the alkoxylation are both alkanolamines such as monoethanolamine, diethanolamine and preferably triethanolamine and also the amines described in DE 2024050 AS such as mono-, di- and trimethylamine, mono-, di-, triethylamine, mono-, di - and tri-n-butylamine, tert.
  • the alkanolamines described are particularly preferred as catalysts.
  • the alkanolamines are usually used in amounts of 0.1 to 5, preferably 0.5 to 1.5,% by weight, based on the fatty acids.
  • the alkoxylation can be carried out in a manner known per se.
  • the fatty acid and the catalyst are placed in a stirred autoclave, which is freed of traces of water by alternately evacuating and flushing with nitrogen before the reaction.
  • the fatty acid is then reacted with ethylene oxide and / or propylene oxide in a molar ratio of 1: 0.5 to 1: 5, preferably 1: 1 to 1: 2, which, after heating, can be metered in portions into the pressure vessel using a siphon.
  • n stands for a number from 0.5 to 5, preferably for a number from 1 to 2.
  • the alkoxylation can be carried out at temperatures in the range from 80 to 180, preferably 100 to 120 ° C. and autogenous pressures in the range from 1 to 5, preferably 2 to 3, bar. After the end of the reaction, it is advisable to stir at the reaction temperature for a certain time to complete the conversion (15 to 90 min). The autoclave is then cooled, decompressed and, if desired, acids such as lactic acid or phosphoric acid are added to the product in order to neutralize the basic catalyst.
  • either exclusively or exclusively propoxylated or also ethoxylated and propoxylated fatty acids are used as starting compounds. If ethoxylated and propoxylated fatty acids are used, they can be random or block compounds.
  • the ratio of ethylene oxide and propylene oxide to be used can be set within a wide range, as long as the degree of alkoxylation n is in the above range.
  • the consistency of the alkoxylated fatty acid can be influenced via the proportion of propylene oxide. As the degree of propylation increases, the softening temperature of the alkoxylated fatty acids becomes lower. If the fatty acids are exclusively propoxylated, even liquid products are obtained, while the exclusively ethoxylated fatty acids are solid compounds.
  • the sulfation of the fatty acid alkylene glycol esters can be carried out using gaseous sulfur trioxide in the manner known for fatty acid lower alkyl esters, preference being given to continuously operating reactors which operate on the falling film principle.
  • the sulfur trioxide is diluted with an inert gas, preferably air or nitrogen, and used in the form of a gas mixture which contains the sulfur trioxide in a concentration of 1 to 8, in particular 2 to 5,% by volume.
  • the molar ratio of fatty acid alkylene glycol ester to sulfur trioxide is generally 1: 1 to 1: 1.3, preferably 1: 1.05 to 1: 1.1.
  • the sulfation is preferably carried out in a continuous falling film reactor at temperatures which are at least 5 to 10 ° C. above the melting point of the fatty acid alkylene glycol esters. As a rule, the sulfation temperatures are up to a maximum of 30 ° C above the melting point of the fatty acid alkylene glycol esters.
  • the sulfation is carried out with a sulfation reagent, in particular with chlorosulfonic acid. The reaction takes place under conditions known to the person skilled in the art, for example in a continuously operating process with approximately stoichiometric amounts of chlorosulfonic acid.
  • the acid esters of the formula (I) obtained after the sulfation are neutralized with bases in such a way that the pH is in the range from 5 and 9, preferably from 6 and 8, during the entire neutralization process. It has proven advantageous to carry out the neutralization in such a way that the acid ester is run into an aqueous solution, the pH of the aqueous solution always being adjusted to pH values between 5 and 9 by metering in the alkaline solution intended for neutralization is held. On an industrial scale, this can be done by simultaneously dosing the liquid acid ester and of the alkaline solution intended for neutralization into the neutralization cycle.
  • An example of such a suitable neutralization circuit can be found in German published patent application DE 4017463 A1.
  • neutralization it has proven to be advantageous to carry out the neutralization at temperatures from 10 ° C. to 40 ° C., preferably at 20 ° C. to 35 ° C.
  • any other neutralization method known to the person skilled in the art such as, for example, spray neutralization, as long as the above pH value for neutralization is maintained.
  • hydroxides such as alkali metal, alkaline earth metal hydroxide or also ammonia can be used and / or also water-soluble organic amines such as mono-, di- and tri-C2-alkanolamines, for example mono-, di- and triethanolamine as well as primary, secondary or tertiary C ⁇ -4-alkylamines.

With the help of a special stirring head, air is stirred into the test solution to be tested, which causes foaming. To measure the foaming kinetics, ie the foam behavior in the beginning, the stirrer is switched off at intervals of 10 seconds during the first 90 seconds in order to read the foam height and liquid level on the scale. The agitator is then switched on again. To determine the foam stability, the foam and liquid height is recorded for a further 5 minutes after the total stirring time of 3 minutes. The foaming kinetics are calculated from the linear part of the gradient line of the average foam volume determined within the first minute at intervals of 10 seconds. It is given in ml / s. The results are summarized in Table 1. Table 1
  • fatty acid polyglycol ester sulfates for alkyl polyglycosides produce better foaming kinetics than ether sulfates (sodium laureth sulfates) and also ensure better foaming behavior in the long term.
