The addition reactions of maleic anhydride to linolic acid were carried out in the presence of activated clay at 180°C. The methyl ester of reaction products was fractionated by TLC. Then, each fraction was identified by mol. wt., saponif. V., and from the GLC, NMR, IR, and UV spectral characteristics.
The activated clay acts as a catalyst for the maleic anhydride addition reaction to linolic acid giving monomaleinized compounds with the structure of cyclohexenic type in more than 50% yield. In the absence of activated clay the reaction products include compounds of various type containing monomaleinized compounds of succinic anhydride type.
