摘　　要：A sun-screening agent isooctyl p-methoxy cinnamate was prepared by reaction of p-methoxyl benzaldehyde with isooctyl acetate using titanium tetrachloride as catalyst. The optimum conditions are as follows： molar ratio of p-methoxyl benzaldehyde to isooctyl acetate and titanium tetrachloride is 1 ： 1.1 ： 0.5; reaction temperature is 30℃; and reaction time is 6 h. The yield of isooctyl p-methoxy cinnamate can reach 98%. The method of the synthesis of isooctyl p-methoxy cinnamate is efficient and economical.A sun-screening agent isooctyl p-methoxy cinnamate was prepared by reaction of p-methoxyl benzaldehyde with isooctyl acetate using titanium tetrachloride as catalyst.
