摘要:
Solvent-free production of carbohydrate partial esters of average esterification degree 1-4 in presence of an alkali metal carbonate/alkali metal hypophosphite catalyst mixture is effected by transesterification of glycoses with fatty acid esters in presence of emulsifiers and a specified catalyst mixture. Solvent-free production of carbohydrate partial esters of average esterification degree 1-4 in presence of an alkali metal carbonate/alkali metal hypophosphite catalyst mixture is effected by the following steps optionally under a protective gas atmosphere (A) forming a catalytically- active system by mixing (ai) an alkali metal carbonate with (aii) a fatty acid alkyl ester of formula R 1>CO-R 2> (I R 1>CO = 6-30C optionally branched, optionally unsaturated acyl and R 2> = 1-5C alkyl) (B) adding to the resulting mixture under constant stirring (bi) 5-12C glycoses, (bii) carbohydrate partial esters as emulsifiers and (biii) alkali metal hypophosphite so as to give a dispersion from which water is drawn off under constant stirring at up to 100[deg]C at up to 50 mbar and (C) effecting esterification at up to 50 mbar and up to 125[deg]C under constant stirring until the content of the fatty acid ester (I) has fallen to at least 8 wt.% of the total composition. An independent claim is also included for shaped bodies comprising (1) the carbohydrate partial ester (2) a suitable emollient for foodstuffs and/or cosmetics (3) 1-10 wt.% of a 16-40C fatty alcohol or a mixture of such fatty alcohols and (4) up to 20 wt.% further additives.본 발명은, 알칼리성 탄산염 및 알칼리성 차아인산염으로 이루어진 촉매 혼합물의 존재 하에서의 알칼리 촉매된 에스테르 교환 반응을 통한, 평균 에스테르화도가 1 내지 4 인 탄수화물 부분 에스테르의 무용매 (solvent-free) 제조 방법에 관한 것이다. 본 발명은 또한 이러한 방법으로 수득된 탄수화물 부분 에스테르의 용도 및 상기 에스테르 기재의 특수한 성형체에 관한 것이다.
