Process for refining organic-solvent containing crude polyol fatty-acid polyester products.

摘要

The present invention pertains to a process for refining organic-solvent containing crude polyol fatty-acid polyester reaction product, comprising the steps of distilling the crude reaction product to substantially remove the organic solvent, and subsequently subjecting the distilled reaction product to a bleaching treatment. The process allows an economic use of bleaching agents while achieving good colour and colour stability of the refined product.
