Description
(54) СПОСОБ ПОЛУЧЕНИЯ СПИРТОВ ШЕРСТЯНОГО ЖИРА(54) METHOD OF OBTAINING ALCOHOL ALCOHOL
Изобретение относитс к способу получени спиртов шерст ного жира, используемых в качестве эффективных эмульгаторов в различных косметичес ких издели х и фармацевтических пре паратах. Известен способ получени спирто шерст ного жира путем каталитического восстановлени сложноэфирных групп восков шерст ного жира в присутствии никельхромового катализато при температуре 250-350°С и давлени 200-300 атм 1. Спирты шерст ного жира, как усре ненный продукт представл ют собой сложную смесь, содержащую спирты, невосстановленные сложные эфиры и побочные продукты реакции - углеводороды в следующем процентном соо ношении: Нормальные, разветвленные спирты С,е - С, Диолы С т е р и и ы Холестерин (С, 7H460 Ди гидрохолест ерин холестакол ( ) Тритерпеновые спирты Ланостерин () Дигидроланостерин ( CgoHsjO) Агностерин (, Дигидроагностерин () Неидентифицированные соединени В состав продукта восстановлени вход т также набольшие количества углеводородов. Наиболее ценными компонентами этого продукта вл ютс свободные спирты, содержание которых характеризуетс гидроксильным числом, наименее ценными - углеводороды. По технической сущности к предложенному способу наиболее близок способ получени спиртов шерст ного жира восстановлением сложноэфирных групп восков шерст ного жира в присутствии медьхромбариевого катализатора при температуре 280-300с к добавлении 200-300 атм. Способ позвол ет получить продукты с гидроксильным числом не выше 140, так как селективность восстановлени сложноэфирных групп восков не превышает 65% 2.The invention relates to a method for producing wool fat alcohols, used as effective emulsifiers in various cosmetic products and pharmaceutical preparations. A known method of producing alcohol wool fat by catalytic reduction of ester groups of wool fat waxes in the presence of nickel chromium catalyst at a temperature of 250-350 ° C and a pressure of 200-300 atm. 1. Alcohols of wool fat, as a moderate product, are a complex mixture, containing alcohols, unrestored esters and by-products of the reaction - hydrocarbons in the following percentages: Normal, branched alcohols C, e - C, Diols Cp and and s Cholesterol (C, 7H460 Di hydrocholesterin cholestacol () T iterpenovye alcohols lanosterol () dihydrolanosterol (CgoHsjO) Agnosterin (, Digidroagnosterin () Unidentified compounds The product recovery input m and the greatest quantity of hydrocarbons most valuable components of the product are free alcohols, the content of which is characterized by a hydroxyl number, the least valuable -. hydrocarbons. technical essence of the proposed method is the closest way to obtain wool fat alcohols by restoring ester groups of wool fat waxes in the presence of a copper-chromium catalyst at a temperature of 280-300s to the addition of 200-300 atm. The method allows to obtain products with a hydroxyl number not higher than 140, since the selectivity of the reduction of wax ester groups does not exceed 65% 2.
