摘　　要：以固体超强酸Fe3+/HZSM-5为催化剂,以乙醇和乙酸为原料合成乙酸乙酯。考察了催化剂用量、酸醇比、反应温度及反应时间对酯化率的影响。结果表明,催化剂用量为(重量)反应液重的5%,酸醇比为2.5∶1,反应温度为110—130℃,反应时间为3h,酯收率为93%.The synthesis of ethyl acetate with ethanol and acetic acid as raw material, Fe3+/HZSM-5 zeolite molecular as catalysts was studied.The effects of the amount of the catalyst used,the ratio of alcohol to acid and the temperature on ester yield are considered.It is shown that, the ester yield will be 94% when the amount of Fe3+/HZSM-5 is 7%(weight), the molar ratio of acetic acid to osopentanol is 2.5∶1, the reaction time is 100-110 ℃.
