PROCESSES FOR THE PRODUCTION OF ALKYLENE GLYCOL IN THE PRESENCE OF ORGANOMETALATE

摘要

In processes for making alkylene glycols by the hydrolysis of alkylene oxides in the presence of selectivity-enhancing metalate anion-containing material, metalate anion can be recovered from the alkylene glycol-containing hydrolysis product by contact with a solid having electropositive complexing sites thereon such as anion exchange resins.
