Allyl acetate is prepared by reaction of allyl alcohol and acetic acid.Then monacetin is oxo-synthesised by hydrogen peroxide solution.The effects of the ratio of reactants,temperature and reaction time on yield of monacetin are studied.The results show that the yield of monacetin can reach 66.0% at 30 ℃,as the molar ratio is n(allyl acetate)∶n(hydrogen peroxide)∶n(sodium tungstate) and the oxidation reaction for 8 h.
