ABSTRACT:
A two-step reaction process for converting ethylene oxide with high selectivity into monoethylene glycol which comprises firstly reacting ethylene oxide with acetone in the presence of a solid acid catalyst to form 2,2-dimethyl-1,3-dioxolane and secondly hydrolyzing the 2,2-dimethyl-1,3-dioxolane with water in the presence of a solid acid catalyst to form monoethylene glycol.
