| Abstract：2-Ethoxyethyl acetate was synthesized from ethylene glycol monoethyl ether and acetic acid under catalysis of solid superacid SO42-／ZrO2 . The influence of reaction conditions such as dosage of catalyst，ratio of acid to alcohol, time and water stripping agent on yield were investigated. The results showed that solid superacid SO42-／ZrO2 exhibited excellent catalytic activity. Under the optimal conditions 2-ethoxyethyl acetate was obtained in 95.8% yield. The catalyst can be recycled for five times without significant yield declining. IR and GC-MS were used for structure identification. |
