标题:通过化学-酶促途径将油酸转化为壬二酸和壬酸
摘要:本文描述了用于将油酸转化为壬二酸和壬酸的化学酶促方法.它代表了臭氧分解的可持续替代方案,目前以工业规模进行反应.经过三个步骤后,以高化学纯度以 44% 的分离率生产壬二酸,避免了柱层析纯化.在第一步中,在 35% H2O2 存在下脂肪酶介导的过油酸生成用于将不饱和酸自环氧化成相应的环氧乙烷衍生物.该中间体进行原位酸催化开环,得到 9,10-二羟基硬脂酸,它很容易从反应介质中结晶出来.二醇衍生物的化学氧化,

标题 :Process for the synthesis of w-Unsaturated nitrile-acid/ester in which two types of cross metathesis are alternated consecutively swing process
发明人：DUBOIS JEAN-LUC; COUTURIER JEAN-LUC
权利人:ARKEMA FRANCE
摘要:The invention relates to a process for the synthesis of a monounsaturated nitrile-ester (acid) by cross metathesis starting from an unsaturated compound I comprising at least one trivalent nitrile, acid or ester functional group, characterized in that it comprises a stage in which two types of cross metathesis are alternated consecutively:n a first type of cross metathesis cm1 with an acrylic compound II chosen from acrylonitrile, acrylic acid or an acrylic ester, one of the compounds I or II comprising a nitrile functional group and the other of these compounds II or I comprising an acid or ester functional group, and a second type of cross metathesis cm2 with a light C 2 to C 4 alkene compound III, preferably with ethylene. nn The invention also relates to a process for the synthesis of an α,ω-amino ester (acid) obtained by a process comprising a stage in which the two types of cross metathesis defined above are alternated consecutively, followed by a hydrogenation stage.
