Process for the preparation of functionalized castor oil derivatives of epoxidized castor oil (echo) by ring opening and / or transesterification

摘要

This invention relates to the development of processes for the preparation of functionalized castor oil derivatives, namely, open-ring glyceryl ricinoleates, alkylenepoxic ricinoleates and open-ring alkyl ricinoleates with adaptive properties of epoxidized castor oil as raw material. using heterogeneous acid-base catalysts. more particularly, the invention employs two reaction chemicals, namely ring opening and transesterification using amberlyst-15 as a solid acid catalyst for the former and oxides derived from caal-double layer hydroxide (caal-ldh) as a solid base catalyst for the last and combinations of these. In addition, both catalysts are reusable and the products are easily separable after reaction by simple physical processes.
