Abstract

A process in which carbon is used to catalyze production of alkylene glycols from alkylene oxides and water. Using this process, carbon may be employed to selectively catalyze the hydrolysis of alkylene oxides, such as ethylene oxide, to monoalkylene gylcols, such as monoethylene glycol. Typically, activated carbon is employed. Suitable forms of activated carbon or other carbon material include powders, granulates, extruded shapes, or mixtures thereof. The process may be carried out as a continuous or batch reaction process.
