Problems solved by technology

[0002] Catalytic oxidation processes are important processes for many commercial chemicals, for example many commercial processes for the epoxidation of olefins have been disclosed in the art, one such process involves certain soluble transition metal compounds (e.g. molybdenum, tungsten , naphthenates of vanadium) in the presence of organic hydroperoxides and olefins, some of the disadvantages of this process include the simultaneous production of alcohol from the hydroperoxide, the recovery of soluble metal catalysts, and the sensitivity of the reaction to water.

Embodiment 1

[0061] The epoxidation of embodiment 1 1-octene

[0062] Add 3% hydrogen peroxide aqueous solution (1.09g) and 1-octene (2.05g) to catalyst B (50mg), stir the mixture at room temperature, after 24 hours, GC analysis shows that 1,2 - Epoxyoctane (18% yield calculated as peroxide).

Embodiment 2

[0063] Example 2 The epoxidation of 1-octene

[0064] Add 3% aqueous hydrogen peroxide solution (1.03g) and 1-octene (2.14g) to catalyst B2 (98mg), stir the mixture at room temperature, and after 24 hours, GC analysis shows that 1,2 - Epoxyoctane (yield 11% calculated as peroxide).

Embodiment 3

[0065] Example 3 Epoxidation of cis-cyclooctene

[0066] Add 10% hydrogen peroxide aqueous solution (1.05g) and cis-cyclooctene (2.44g) in catalyst B2 (91mg), stir the mixture at room temperature, after 24 hours, GC analysis shows that there is cyclooctene oxide (in the form of peroxide The calculated yield was 33%).

Abstract

A process for oxidizing organic compounds is disclosed. Hydrogen peroxide is used to oxidize an oxidizable organic substrate in the presence of a silica-modified titania / silica-containing catalyst. A method for preparing a catalyst using a copolymer of diethoxysilane and ethyl titanate is also disclosed.

Description

field of invention [0001] The present invention relates generally to methods of oxidizing organic compounds, and more particularly to methods of oxidizing oxidizable organics using hydrogen peroxide in the presence of silica-modified titania / silica-containing catalysts, and the use of di A method for preparing a catalyst from a copolymer of ethoxysilane and ethyl titanate. background of the invention [0002] Catalytic oxidation processes are important processes for many commercial chemicals, for example many commercial processes for the epoxidation of olefins have been disclosed in the art, one such process involves certain soluble transition metal compounds (e.g. molybdenum, tungsten , naphthenate of vanadium) in the presence of organic hydroperoxides and olefins, some of the disadvantages of this process include the simultaneous production of alcohol from the hydroperoxide, the recovery of soluble metal catalysts, and the sensitivity of the reaction to water.
