ABSTRACT:
A continuous process for making alkylene glycols by the hydrolysis of alkylene oxides in the presence of selectivity-enhancing organometalate wherein the alkylene glycol-containing hydrolysis product contains organometalate comprises recovering organometalate by extraction with a water-immiscible solvent, separating the resulting organometalate-containing solvent into an organometalate-lean stream for reuse in the extraction and an organometalate-rich stream for reuse in the hydrolysis.
