Method for commercial preparation of conjugated linoleic acid using spent alkali transesterification catalyst

摘要

Conjugated linoleic acid is readily prepared by mixing crude alkaline glycerol solution derived as a byproduct of triglyceride transesterification and a linoleate rich triglyceride, ester, soap, phospholipid, fatty acid, or wax and heating the mixture sufficiently to conjugate the linoleate double bonds. The reaction produces a favorable isomer mixture enriched in 10,12-trans,cis octadecadienoic and 9,11-cis,trans-octadecadienoic acids.
