| Abstract：The synthesis of methyl salicylate, AlCl 3/D 72 Resin as catalyst,the influences of Catalyst dosage, reaction time, reaction temperature and the ratio of alcohol to acid on synthetising methyl salicylate were studied. The experiment results showed that the optimum condition was as follows: the quality proportion of salicylic acid and catalyst dosage 100∶1, reaction time 3h, reaction temperature 65～70℃, the ratio of alcohol to acid 3～4∶1 (not carrying water reagent) or 1.5～2∶1 (with carring water reage... |
