Secondly, the fatty acid methyl esters were partially hydrotreated catalytically to transform poly-unsaturated fatty acid such as linoleic acid into oleic acid the olefin cross-metathesis then transformed the oleic acid methyl ester (oame) into 1-decene and 1-decenoic acid methyl ester (dame. Unsaturated fatty ester is oleic acid that is converted into methyl oleate in the biodiesel process the double bond of the fatty acid ester is ideal for use with metathesis reactions like self- and cross-metathesis the reactions of the fatty acid esters produce simple alkenes, mono- and diesters.
