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 glycerolsolution derived as a byproduct of triglyceride transesterification and alinoleate rich triglyceride, ester, soap, phospholipid, fatty acid, or wax andheating the mixture sufficiently to conjugate the linoleate double bonds. Thereaction produces a favourable isomer mixture enriched in 10, 12-trans,cisoctadecadienoic and 9,11- cis, trans-octadecadienoic acids.
