ABSTRACT:
The present disclosure relates to the catalytic hydration of alkylene oxides, in particular ethylene oxide for the production of glycols using a catalyst comprising a copper promoted aluminum phosphate. In certain instances the isomerization activity of the catalyst can be reduced by the incorporation of small quantities of alkali or alkaline earth metals as inhibitors for such process.
