METHOD FOR PRODUCING CONJUGATED LINOLEIC ACID GLYCERIDES |
摘要 |
<p>Processes for preparing conjugated fatty acid glycerides comprising: (a) isomerizing a fatty acid lower alkyl ester corresponding to the general formula (I) in the presence of a basic catalyst at a temperature of from 100 to 160° C., to form a conjugated fatty acid lower alkyl ester: <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>CO-OR<SUP>2</SUP> (I)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUP>1</SUP>CO represents an acyl radical having from 16 to 22 carbon atoms and at least two carbon-carbon unsaturations and R<SUP>2 </SUP>represents an alkyl radical having from 1 to 4 carbon atoms; and (b) transesterifying the conjugated fatty acid lower alkyl ester with glycerol to form a conjugated fatty acid glyceride, wherein a lower alkanol corresponding to the general formula R<SUP>2</SUP>OH is formed, wherein R<SUP>2 </SUP>is as defined above, and the lower alkanol is continuously removed from the transesterification reaction; are described.</p> |
