Definitions

  • the invention relates to a process for the preparation of alkyl sulfate pastes with improved flowability by sulfonating aliphatic alcohols and unsaturated fatty acid glyceride esters as well as subsequent neutralization and hydrolysis of the reaction products formed.
  • Anionic surfactants of the alkyl sulfate type especially those containing alkyl radicals with 16 to 18 carbon atoms, show excellent detergent properties and are used in particular in powder detergents.
  • aqueous alkyl sulfate pastes are used.
  • the aqueous surfactant pastes have the highest possible solids content.
  • alkyl sulfate pastes can only be concentrated up to a certain solids content. Above this limit, the viscosity generally reaches such high values that the pumpability of the surfactant solutions is no longer guaranteed, even at elevated temperatures. There has been no lack of attempts in the past to solve the problem of high viscosity of anionic surfactant pastes.
  • Viscosity reducers are sulfonated aromatic compounds [DE-A-23 05 554], cumene sulfonate or acidic phosphoric acid esters [DE-B-16 17 160], polyhydric alcohols, carboxylic acids or esters thereof [EP-A-0008060] or Mono- and / or disulfates of polyalkylene glycol ethers [EP-B-0024711].
  • the object of the invention was therefore to provide a method for producing alkyl sulfate pastes with improved flowability.
  • the invention relates to a process for the preparation of alkyl sulfate pastes with improved flowability, which is characterized in that mixtures containing
  • the aliphatic primary alcohols to be used according to the invention as component a) are fatty alcohols, such as, for example, capron alcohol, caprylic alcohol, capric alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol or behenyl alcohol.
  • fatty alcohols having 12 to 18, preferably 16 to 18, carbon atoms is preferred.
  • alcohols are also suitable as alcohols.
  • technical alcohol cuts such as those which occur, for example, in the hydrogenation of technical fatty acid methyl ester mixtures of natural origin or of aldehydes from Roelen's oxosynthesis.
  • the use of technical coconut or tallow alcohol cuts is preferred.
  • These include such primary fatty alcohols understand, which have the following C-chain distribution on average:
  • the fatty acid glyceride esters to be used as component b) according to the invention are unsaturated mono-, di- and / or triglycerides with iodine numbers from 60 to 210, preferably 100 to 130, which can be of natural or synthetic origin.
  • the fatty acid component can contain 16 to 22 carbon atoms and 1, 2 or 3 double bonds. Examples include the glycerides of palmitoleylic acid, oleic acid, elaidic acid, petroselinic acid, ricinoleic acid, linoleic acid, linolenic acid or erucic acid.
  • these glycerides can also be in the form of technical mixtures, for example as rapeseed oil, sunflower oil, olive oil, peanut oil, coriander oil, cottonseed oil, castor oil or fish oil.
  • the fatty acid component can also contain fractions of saturated fatty acids with 6 to 22 carbon atoms. Preference is given to the use of new rape oil rich in oleic acid.
  • components a) and b) can be used in a weight ratio of 99: 1 to 50:50 be used.
  • Alkyl sulfate pastes with particularly advantageous performance properties are obtained if the components are used in a: b ratio of from 95: 5 to 70:30, in particular from 95: 5 to 90:10.
  • the sulfonation of the mixtures comprising components a) and b) is carried out with gaseous sulfur trioxide in the manner known for fatty acid low alkyl esters [J. Falbe (ed.), "Surfactants in consumer products", Springer Verlag, Berlin-Heidelberg, 1987, p 61-63], with reactors which operate according to the falling film principle being preferred.
  • 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 sulfonating agent in a concentration of 1 to 8, in particular 2 to 5,% by volume.
  • the molar ratio of the mixtures comprising the components a) and b) to the gaseous sulfur trioxide can be 1: 0.95 to 1: 1.5. be.
  • operating conditions of 1: 1.05 to 1: 1.3 have proven to be optimal.
  • the sulfonation is carried out at temperatures from 50 to 90, preferably 40 to 80 ° C.
  • the acidic sulfonation products obtained during the sulfonation are stirred into aqueous bases, neutralized and adjusted to a pH of 7.5 to 10.5.
  • bases for the neutralization come 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-C2-4-alkanolamines, for example mono- , Di and triethanolamine and primary, secondary or tertiary C1.4 alkylamines.
  • the neutralization bases are preferably used in the form of 5 to 55% by weight aqueous solutions, 5 to 25% by weight aqueous sodium hydroxide solutions being preferred.
  • the aliphatic alcohols and the fatty acid glyceride esters are sulfonated together, the corresponding alkyl sulfates are formed.
  • the sulfonation products can be bleached in a manner known per se by adding hydrogen peroxide or sodium hypochlorite solution. Based on the solids content in the solution of the sulfonation products, 0.2 to 2% by weight of hydrogen peroxide, calculated as a 100% substance, or corresponding amounts of sodium hypochlorite are used.
  • the pH of the solutions can be adjusted using suitable buffering agents, e.g. B. be kept constant with sodium phosphate or citric acid. To stabilize against bacterial contamination, conservation is also recommended, e.g. B. with formaldehyde solution, p-hydroxybenzoate, sorbic acid or other known preservatives.
  • the sulfur trioxide was expelled from a corresponding amount of 65% by weight oleum by heating, diluted to a concentration of 5% by volume with nitrogen and introduced into the starting product within 50 minutes.
  • the resulting approx. 25% by weight paste was bleached with 2% by weight, based on the solids content of the paste, 35% by weight hydrogen peroxide solution.
  • the product was then adjusted to a pH of 7.5 using hydrochloric acid and buffered with 1% by weight, based on the solids content, of citric acid. Details of the reaction batches and the characteristics of the products are summarized in Tables 1 and 2.
  • the anionic surfactant content (WAS) and the unsulfonated proportions (US) were determined according to the DGF standard methods, Stuttgart, 1950-1984, H-III-10 and G-II-6b.

Abstract

On obtient des pâtes de sulfate d'alkyle ayant une fluidité améliorée en sulfonant avec de l'anhydre sulfurique gazeux des mélanges qui contiennent: a) 50 à 99 % en poids d'au moins un alcool primaire aliphatique ayant 6 à 22 atomes de carbone et b) 1 à 50 % en poids d'au moins un ester glycéride d'acide gras insaturé dérivé d'acides gras ayant 16 à 22 atomes de carbone et 1, 2 ou 3 liaisons doubles. Les produits de la réaction sont ensuite neutralisés et hydrolysés avec des bases aqueuses, de façon à donner des pâtes ayant une concentration en matières solides comprise entre 30 et 80 % en poids.
