Title:
プロピレンのプロピレンオキシドへの直接酸化方法、およびその方法で使用する大粒径チタンシリカライト触媒
Document Type and Number:
Japanese Patent JP2006513987
Kind Code:
A
Abstract:
Large crystals of titanium silicalite or intergrowths of intergrown smaller crystals, having a mean particle size greater than 2 mum, have been found catalytically effective at commercially reasonable rates for the epoxidation of olefins in the presence of hydrogen peroxide. Crystals synthesized with a silica source having a low sodium content exhibit high levels of production and selectivity. The crystals have a low attrition rate and are easily filterable from a product stream.
