PROCESS FOR THE PREPARATION OF ALKYLENE GLYCOL

摘要

The invention provides a process for the preparation of an alkylene glycol from an alkene wherein conversion of alkylene oxide to alkylene glycol occurs in an alkylene oxide absorber and optionally in further reactors, and alkylene glycol is extracted from fat absorbent by contacting the fat absorbent with a lean solvent, thereby producing fat solvent, recovering alkylene glycol from the fat solvent and recycling the lean solvent.
