杂原子介孔分子筛的制备及其对苯羟化反应的催化性能

Preparation of heteroatom mesoporous molecular sieves and its catalytic performances in oxidation of benzene to phenol

以十六烷基三甲基溴化铵为模板剂,在碱性条件下合成了过渡金属取代的MCM-41和MCM-48,研究了所得产物对以过氧化氢氧化苯直接合成苯酚反应的催化活性。并详细考察了反应的时间、温度、溶剂等对催化反应的活性的影响。

Using cetyltrimethyl-ammonium bromide as template, sodium hydroxide as base medium,we synthesized transition metal substituted MCM-41 and MCM-48, and utilized the resulted materials to hydroxylate benzene to phenol with hydrogen peroxide as oxidant. In this paper, the reaction parameters including time,temperature,solvent which influence the catalytic activity were investigated.
