General description

Methyl octanoate is a saturated organic compound that belongs to the class of fatty acid methyl ester (FAMEs). It can be prepared by the esterification of octanoic acid with methanol in the presence of an acid catalyst.

Application

Methyl octanoate can be used as:
  • A reactant to prepare C7 and C8 hydrocarbons by catalytic decarboxylation/decarbonylation reactions in the presence of Pt/Al2O3 catalyst.
  • A component of biodiesel −bioethanol surrogate fuel model to study its kinetics of oxidation.
