| Abstract: | Glycidol was synthesized from ally alcohol and 30% hydrogen peroxide in the presence of mesoporous molecular sieve supported sodium tungstate.The technology conditions of epoxidation for allyl alcohol(AAL),such as solvent,temperature,catalyst amount,reactant ratio,and reaction time,were studied.The experiment results showed that the yield of glycidol reach 92% under reaction condition as H2O solvent,323 K,catalyst amount 50 mg,ally alcohol 1mL,H2O2 2.7mL,reaction time 10 h. |
