The preparation of cinnamic acid, palmitic acid and acid carboxylate of 14,16-hentriacontanedione were studied in dichloromethane/ methanol and 2-methyl tetrahydrofuran/ methanol (DCM/MeOH and 2-mTHF/MeOH). Hence, this paper demonstrated the alkaline hydrolysis (using NaOH and KOH) of esters in organic solvents (DCM/MeOH and 2-mTHF/MeOH). Although the aromatic ester methyl cinnamate was more readily hydrolysed, however same condition at longer time gave complete hydrolysis of the methyl palmitate and methyl acrylate and dimethyl itaconate modified 14,16-hentriacontanedione. Therefore, DCM/MeOH and 2-mTHF/DCM are quite suitable for the hydrolysis of fatty esters.
