PROCESS FOR THE PREPARATION OF MONOETHYLENE GLYCOL

摘要

The invention provides a process for the preparation of monoethylene glycol from sucrose comprising the steps of: i) hydrolyzing sucrose to form a reaction product stream comprising glucose and fructose; ii) separating the reaction product stream comprising glucose and fructose into a fructose or fructose derivative rich stream and a glucose rich stream; and iii) contacting the glucose rich stream with hydrogen in a reactor in the presence of a solvent and a catalyst system with catalytic hydrogenation abilities to produce a product stream comprising monoethylene glycol.
