Abstract
En un proceso para la epoxidación de propeno haciendo reaccionar propeno con peróxido de hidrógeno en presencia de un solvente metanólico y un catalizador de epoxidación de zeolita de titanio, las etapas de: separar de la mezcla de reacción un óxido de propeno crudo y una mezcla de solventes que comprende metanol, agua y peróxidos; someter la mezcla de solventes a una hidrogenación catalítica para hidrogenar peróxidos, proporcionar una mezcla de solventes hidrogenada que comprende entre 1 y 1000 mg/kg de acetaldehído; separar el solvente hidrogenado en al menos una etapa de destilación, agregando un ácido a la mezcla de solventes hidrogenada o a por lo menos una etapa de destilación, proporcionando un metanol recuperado como un producto de cabeza; hacer pasar el metanol recuperado a través de un lecho de una resina de intercambio iónico ácido, proporcionando un metanol tratado; y reciclar el metanol tratado a la reacción de epoxidación para evitar la desactivación del catalizador de la epoxidación mediante el reciclado del acetaldehído con el metanol.In a process for the propene epoxidation by reacting propene with hydrogen peroxide in the presence of a methanolic solvent and a titanium zeolite epoxidation catalyst, the steps of: separating from the reaction mixture a crude propene oxide and a mixture of solvents comprising methanol, water and peroxides; subjecting the solvent mixture to catalytic hydrogenation to hydrogenate peroxides, providing a hydrogenated solvent mixture comprising between 1 and 1000 mg / kg acetaldehyde; separating the hydrogenated solvent in at least one distillation stage, adding an acid to the hydrogenated solvent mixture or at least one distillation stage, providing recovered methanol as a head product; passing the recovered methanol through a bed of an acidic ion exchange resin, providing a treated methanol; and recycle treated methanol to the epoxidation reaction to prevent deactivation of the epoxidation catalyst by recycling acetaldehyde with methanol.
