Studies on synthesis of titanosilicate catalyst for the higly selective production of hydroquinone by phenol oxidation

本研究的目的是开发具有MSE拓扑结构的含ti MCM-68的制备方法，作为过氧化氢苯酚氧化高选择性生产对苯二酚的氧化催化剂。结果表明，Ti-MCM-68的12元环微孔的形状选择性导致了对苯二酚的高选择性生成，通过增强其疏水性可以提高Ti-MCM-68的催化收率。

The aim of this research is development of preparation methodology in Ti-containing MCM-68 with an MSE topology as a oxidation catlayst with highly selective production of hydroquinone in the phenol oxidation with hydrogen peroxide.It is confirmed that shape-selectivity in 12-membered ring micropores of Ti-MCM-68 leads to highly selective production of hydroquinone, and the catalytic yield in Ti-MCM-68 can be improved by the enhancement of its hydrophobicity.
