Procedure

Mixture of methyl esters, namely methyl myristate (0.5%), methyl palmitate (4.9%), methyl oleate (83.6%) and methyl linoleate (11.0%) exhibit low pour point of −21° C. This methyl esters mixture was obtained via acid-catalysed direct esterification of technical grade of oleic acid (with purity ≈80%) with methanol.
