Study on catalytic synthesis of pentyl p-hydroxybenzoate |
| |
| Abstract: | The pentyl p hydroxybenzoate had been synthesized from pentanol and p hydroxybenzoic acid with yellow ferric vitriol as catalyst. The effect of reaction temperature and time, molar ratio of p hydroxybenzoic acid to pentanol and the dose of catalyst on the esterification are studied.The results showed that the reaction at 110 ～ 160 ℃ for 2 h,molar ratio of p hydroxybenzoic acid to pentanol was 3∶1,the catalyst dose 1.5 g,the yield of esterification reached 93.3%? |
