Abstract
В заявке описано, что проведение в способе эпоксидирования пропена путем введения пропена в реакцию с пероксидом водорода в присутствии растворителя-метанола и титансодержащего цеолитного катализатора эпоксидирования стадий: выделения из реакционной смеси неочищенного пропеноксида и смеси растворителей, содержащей метанол, воду и пероксиды; обработки смеси растворителей путем каталитического гидрирования с целью гидрирования указанных пероксидов с получением гидрированной смеси растворителей, содержащей от 1 до 1000 мг/кг ацетальдегида; разделения гидрированной смеси растворителей при проведении по меньшей мере одной стадии дистилляции при добавлении кислоты к гидрированной смеси растворителей или при проведении по меньшей мере одной стадии дистилляции с получением извлеченного метанола в виде головного продукта; пропускания извлеченного метанола через слой кислой ионообменной смолы с получением обработанного метанола; и рециркуляции обработанного метанола на стадию проведения реакции эпоксидирования, предотвращает инактивацию катализатора эпоксидирования, возникающую вследствие рециркуляции ацетальдегида вместе с метанолом.The application describes that carrying out in the method of epoxidation of propene by introducing propene into a reaction with hydrogen peroxide in the presence of a solvent-methanol and a titanium-containing zeolite catalyst for epoxidation of the stages: separation from the reaction mixture of crude propene oxide and a mixture of solvents containing methanol, water and peroxides; treating the solvent mixture by catalytic hydrogenation to hydrogenate said peroxides to obtain a hydrogenated solvent mixture containing from 1 to 1000 mg / kg acetaldehyde; separating the hydrogenated solvent mixture in at least one distillation step by adding acid to the hydrogenated solvent mixture or in at least one distillation step to obtain recovered methanol as a top product; passing the recovered methanol through a bed of acidic ion exchange resin to obtain treated methanol; and recycling the treated methanol to the epoxidation reaction step, prevents inactivation of the epoxidation catalyst resulting from recycling acetaldehyde along with methanol.
