The catalytic addition reaction of diester of fumaric acid to safflower fatty acid methyl esters by flow method was investigated. It was found that the addition of diethyl fumarate to safflower fatty acid methyl esters is easily carried out by continuously passing the mixed sample of the methyl esters and diethyl fumarate at molar ratio of 1 : 1 over a high surface-area synthetic silica-alumina catalyst composed of 70% of SiO2 and 29% of Al2O3. The adduct separated by column chromatography was analyzed to have a cyclohexene ring structure by IR, NMR, and MS spectral measurement, and was confirmed to be formed by the Diels-Alder addition of diethyl fumarate to conjugated octadecadienoate.
