The invention relates to a process for the production of glycerol carbonate esters corresponding to formula (I):
in which R is hydrogen or an alkyl or alkenyl group containing 1 to 23 carbon atoms, which may be linear or branched, characterized in that a compound corresponding to formula (II):
in which Y is a group —O—CO—Z and Z is hydrogen or an alkyl or alkenyl group containing 1 to 3 carbon atoms, which may be linear or branched, is transesterified with dimethyl carbonate or diethyl carbonate and an alkyl ester corresponding to formula (IV):
in which R is as defined above and X is an alkyl or alkenyl group containing 1 to 8 carbon atoms, which may be linear or branched, with the proviso that the group R of compound (IV) is different from the group Z of compound (II), in the presence of a transesterification catalyst.
该发明涉及一种生产与式(I)对应的
甘油碳酸酯的方法:其中R为氢或含有1至23个碳原子的烷基或烯基基团,可以是直链或支链,其特征在于将与式(II)对应的化合物:其中Y为基团—O—CO—Z,Z为氢或含有1至3个碳原子的烷基或烯基基团,可以是直链或支链,与二甲基
碳酸酯或乙基
碳酸酯和与式(IV)对应的烷基酯进行酯交换反应:其中R如上所述,X为含有1至8个碳原子的烷基或烯基基团,可以是直链或支链,但化合物(IV)的基团R与化合物(II)的基团Z不同,在酯交换催化剂存在下进行。
