Abstract Cetyl phthalate was prepared from phthalic anhydride and cetyl alcohol as raw materials catalyzed by non-acid catalyst.The effects of reaction temperature,reaction time,catalyst and the molar ratio of raw materials on the yield of product were discussed.The experimental results showed that the yield of cetyl phthalate was up to 98% when the reaction temperature was 220 ℃,the ratio of cetyl alcohol to phthalic anhydride was 3.0,the mass concentration of catalyst was 0.2%,the reaction time was 4.5 h,the adding temperature of catalyst was over 180 ℃.The whole process can be carried out under mild reaction condition,easy manipulation,post-treatment,short reaction time and without any waste gas, water or solid produced.The IR spectrogram of the product was identical with that of the target product.
