摘要
以水杨酸和正丁醇为原料,硫酸氢钠为催化剂,合成了水杨酸正丁酯。考察了正丁醇与水杨酸摩尔比、反应时间、催化剂用量对酯化收率的影响。通过实验得到最佳工艺条件为:正丁醇与水杨酸摩尔比为1.6∶1,反应时间为4h,催化剂用量为水杨酸用量的6%(质量分数),水杨酸正丁酯收率可达60.66%。
Butyl salicylate was synthesized from salicylic acid and n-butanol catalyzed by sodium bisulfate.The effect of the molar ratio of n-butanol to salicylic acid,the reaction time,the amount of catalyst was discussed. Optimal conditions were obtained：the molar ratio of n-butanol to salicylic acid was 1.6：1, the reaction time was 4h and the mass ratio of catalyst to salicylic acid was 6%, the yield of butyl salicylate was 60.66%.
