| Abstract: | The process for preparing methylheptenone by hydrolytic cracking of prenyl mesityl oxide was studied.The influencing factors of cracking such as the molar ratio of reactants,hydrolytic reaction time,composition of reactants,etc were studied.The results showed that the optimal reaction parameters were:n(prenyl mesityl oxide):n(ethanolamine):n(sodium hydroxide):n(water) = l: 2:0.07:2,reaction temperature 95 - 120℃,reaction time 4 h.Under these conditions,the yield of methylheptenone exceeds 98%. |
