Abstract

In a process for the epoxidation of propene by reacting propene with hydrogen peroxide in the presence of a methanol solvent and a titanium zeolite epoxidation catalyst, the steps of: separating from the reaction mixture a crude propene oxide and a solvent mixture comprising methanol, water and peroxides; subjecting the solvent mixture to a catalytic hydrogenation for hydrogenating peroxides, providing a hydrogenated solvent mixture comprising from 1 to 1000 mg/kg of acetaldehyde; separating the hydrogenated solvent in at least one distillation stage, adding an acid to the hydrogenated solvent mixture or to at least one distillation stage, providing a recovered methanol as an overhead product; passing the recovered methanol through a bed of an acidic ion exchange resin, providing a treated methanol; and recycling the treated methanol to the epoxidation reaction prevent deactivation of the epoxidation catalyst by recycling acetaldehyde with the methanol.
