Abstract

Настоящее изобретение обеспечивает способ получения этиленгликоля путем гидролиза монометилового эфира этиленгликоля. Способ предусматривает пропускание свежего сырьевого материала, содержащего монометиловый эфир этиленгликоля и воду, через реакционную зону, загруженную твердым кислотным катализатором, для реакции при следующих условиях; разделение прореагировавшей смеси посредством системы разделения с получением целевого продукта - этиленгликоля, побочных продуктов, содержащих метанол, диметиловый эфир и производные на основе этиленгликоля, и непрореагировавшего сырьевого материала, содержащего монометиловый эфир этиленгликоля и воду; перемещение целевого продукта - этиленгликоля - в систему сбора продукта и перемещение метилового спирта и диметилового эфира в побочных продуктах в систему сбора побочных продуктов; и после смешивания со свежими сырьевыми материалами, содержащими монометиловый эфир этиленгликоля и воду, производные на основе этиленгликоля в побочных продуктах и непрореагировавший сырьевой материал, содержащий монометиловый эфир этиленгликоля и воду, рециркулируют в реакционную зону для проведения получения этиленгликоля путем гидролиза монометилового эфира этиленгликоля. Настоящее изобретение обеспечивает новый способ для осуществления получения этиленгликоля путем гидролиза монометилового эфира этиленгликоля. И в способе катализатор имеет длительный срок службы и хорошую стабильность.
