Abstract

The present invention relates to a catalyst for catalyzing ethylene oxide hydration to prepare ethylene glycol and its preparation method. Said catalyst composition includes anion-exchange resin, silicate and permanganate, their mixing ratio is 100:4-8:0.1-0.5. Its catalysis activity and selectivity can be up to above 98%.

Description

Catalyst for preparing ethylene glycol by hydration of ethylene oxide and preparation method thereof technical field The invention relates to a catalyst for catalyzing the hydration of ethylene oxide to prepare ethylene glycol and a preparation method thereof, in particular to a modified anion exchange resin for catalyzing the hydration of ethylene oxide to prepare ethylene glycol and a preparation method thereof. Background technique Ethylene glycol (EG) is an important petrochemical raw material, one of the important derivatives of ethylene, and the product with the largest output among diols. It is widely used in the production of synthetic fibers, paints, adhesives, surface active It is an indispensable intermediate for products such as agents and explosives, and can also be directly used as a solvent and antifreeze. At present, more than 85% of the industrial production methods of ethylene glycol at home and abroad adopt the EO / EG technology developed by SD company o...
