摘要
强酸性条件下 ,在 4 0℃水浴中 ,以无水乙醇和异丙醇为混合剂 ,合成了n(Si)∶n(Ti)为 30的超微粒介孔分子筛Ti-MCM - 41。研究了超微粒介孔分子筛Ti-MCM - 41在苯乙烯与双氧水反应中的催化行为 。
The ultrafine mesoporous molecular sieve Ti-MCM-41 was prepared in solvent mixture of non-aqueous alcohol and isopropanol at 40 ℃ in the presence of strong acid ,in which the molar ratio of silicate to titanium was 30 The catalytic behaviors of the molecular sieve Ti-MCM-41 in the oxidation of styrene with hydrogen peroxide were studied The experiments showed that styrene could be oxidized to acetophenone and benzaldehyde by hydrogen peroxide The effects including catalyst amount, reaction time, reacton temperature and H 2O 2 concentrate on conversion of styrene were examined.
