| Abstract: | Phosphorus molybdenum acid supported on activated carbonas is used as the catalyst for preparing cyclohexyl acetate from acetic acid and cyclohexyl alcohol. The optimum conditions are determined as follows:hexamethlent alkyl as dehydrating agent,2% catalyst of the total mass of reactants, the molar ratio of the alcohol and acid 1:1.1, reaction temperature 110?and reaction time 90?min. The conversion rate of acetic acid is (88.5%),and the purity of product over 98%. |
