| Abstract: | Under the microwave radiation condition, single octademaleat was synthesized with malefic anhydride and octadecanol as raw materials and ptoluene sulphonic acid as catalyst.Through the orthogonal experimental design, the effect of the esterification rate was investigated under different conditions of the microwave power, the irradiation time, contents of catalyst and the rate acid to alcohol.The structure of the product was characterized with IR.The results showed that single octademaleat was synthesized su... |
