摘要
采用四氯化钛催化对甲氧基苯甲醛和乙酸异辛酯合成了一种防晒剂对甲氧基肉桂酸异辛酯,结果表明:n(对甲氧基苯甲醛)∶n(乙酸异辛酯)∶n(四氯化钛)=1∶1.1∶0.5、反应温度30℃、反应时间6 h的优化条件下,对甲氧基肉桂酸异辛酯的产率达到了98%。
A sun-screening agent, isooctyl p-methoxy cinnamate, was prepared by reaction ofp-methoxybenzaldehyde with isooctyl acetate using titanium tetrachloride as catalyst. The results showed that the yield of isooctyl p-methoxy cinnamate can reach 98% under the optimum conditions i.e. the molar ratio ofp-methoxybenzaldehyde : isooctyl acetate : titanium tetrachloride is 1 : 1.1 : 0.5, the reaction temperature is 30℃ and the reaction time is 6 h.
