| Abstract: | Lauryl phenylacetate was synthesised from phenylacetic acid and lauryl alcohol by the catalyst of solid superacid SO_4~2-/TiO_2.The effects of raw materials mole ratio,reaction time and amount of catalyst on the yield were investigated.The optimum conditions are as follows:the mole ratio of alcohol to acid is 3.0∶1,the amount of catalyst is 5%,reaction time is 3 h.The esterification is over 90.8% under the optimum conditions. |
