Ethylidene diacetate is prepared by treating at least one member of the group consisting of methyl acetate and dimethyl ether with carbon monoxide in the presence of a source of halide under substantially anhydrous conditions.

Process for preparing ethylidene diacetate

A supported silver catalyst for oxidation of ethylene to ethylene oxide is prepared by impregnation of the support, activation, and solvent washing, with each step being carried out at a relatively low temperature. Silver so deposited has an average particle diameter of about 0.5-0.7 microns and is capable of being promoted by post-deposition of alkali metals such as cesium, rubidium, and potassium.

Process for preparing a silver catalyst

An improved process for the catalytic dehydration of alcohols to form unsaturated organic compounds is provided in which an alcohol is dehydrated in the presence of alumina catalysts which are pre-treated with an organic silylating agent at elevated temperature.

Catalytic process for dehydration of alcohols

A supported silver catalyst, having particular utility in the production of ethylene oxide by the controlled, vapor phase, partial oxidation of ethylene employing molecular oxygen as the oxidant, is prepared by impregnation procedures. After impregnation, the catalyst is activated by thermal pyrolysis in an inert atmosphere and, subsequently, an alkali metal promoter, preferably a potassium, rubidium, and/or cesium salt is added to enhance catalyst performance.

Process for the preparation of a supported silver catalyst

Process for preparing unsaturated esters by reacting an olefin having an allylic hydrogen atom with an ester forming material in the presence of oxygen and a catalyst selected from the group consisting of mercury, selenium or tellurium. The unsaturated ester may be converted to a polyunsaturated compound by pyrolysis.
