| Abstract: | Ammonium ferric sulfate (NH4Fe(SO4)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 (NH4Fe(SO4)2*12H2O) 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. |
