摘要:
An improved process for the production of unsaturated carboxylic acids and unsaturated nitrites from their corresponding C3 to C5 alkanes, or mixtures of C3 to C5 alkanes and alkenes, that involves a multi-stage reaction system which employs both separation of the oxidation product from one or more intermediate effluent streams, as well as feeding additional oxygen to reaction zones subsequent to the first reaction zone.

摘要:
A polymeric catalyst, and methods of using the catalyst, comprising at least one of a monosulfonated ion exchange resin, monosulfonated gel, and macroreticular resin having a particle size of less than 560 μm and metal impregnated within the resin, where the metal is palladium, platinum, iridium, rhodium, ruthenium, copper, gold, and/or silver.
摘要:
A method for preparing a ketone, and ketone produced therefrom, comprising charging to a column a catalyst of an ion exchange resin impregnated with a metal chelate, adding solvent to the column, and initiating production of the ketone by flowing the solvent and hydrogen through the column.
