【摘要】 硫酸铁铵能够代替硫酸用作酯化催化剂。研究了 NH4 Fe(SO4 ) 2 · 1 2 H2 O催化合成乙酸环己酯的反应条件 ,当乙酸、环己醇和硫酸铁铵的摩尔比为 1∶ 0 .44∶ 0 .0 2 ,以环己烷为溶剂 ,回流分水 6 0min,乙酸环己酯收率达 87.2 % ,在相同反应条件下 ,合成了甲酸环己酯 (收率为 6 8.5 % )、丙酸环己酯(收率为 5 9.4% )和丁酸环己酯 (收率为 2 1 .6 % )。更多还原

【Abstract】 Ammonium ferric sulfate (NH 4Fe(SO 4) 2) can be used as catalyst for the esterification instead of sulphuric acid.The reaction conditions of synthesizing cyclohexyl acetate catalyzed with ammonium ferric sulfate dodecahydrate (NH 4Fe(SO 4) 2·12H 2O) are studied .The yield of cyclohexyl acetate can reach 87.2% under mole ratio of acetic acid,cyclohexyl alcohol and ammonium ferric sulfate is 1∶0.44∶0.02,cyclohexane as solvent ,refluxing and segregating water for 60 min.In same reaction conditions,the cyclohexyl formate (68.5%),cyclohexyl propionate (59.4%) and cyclohexyl butyrate (21.6%) are synthesized.更多还原
