| Abstract: | Using hydrogen peroxide as oxidant,Na-Y,Na-ZSM-5,Na-β,MCM-41,MCM-22,SBA-15 six molecular sieve promoted epoxidation of allyl alcohol,3-methyl-2-butenl-1-ol and methyl heptenone.We investigated the promotion of molecular sieve for the conversion and selectivity of epoxidation of the three alkenes.The results indicated that in the six molecular sieves,most of them could promote the epoxidation of the three alkenes,and the promotion of SBA-15 for the epoxidation of the three alkenes was obvious.At last,we discussed the promotion of SBA-15 for allyl alcohol at different reaction time,different temperature,different quantity of SBA-15 and hydrogen peroxide.The results showed that the best promotion condition was 4 h,50 ℃,nH2O2∶n底物=1.5. |
