ABSTRACT:
A process for the preparation of alkylene glycols by reacting an alkylene oxide with water in the presence of a catalytic composition comprising a macrocyclic chelating compound complexed with an ionic compound the anion of which is catalytically effective under the reaction conditions. Preferably, the macrocycle is a crown ether or a cryptate and the anion is selected from the group of halogenides, carboxylates having from 1-20 carbon atoms, hydrogen carbonate, hydrogen sulphite, hydrogen phosphate and metalates.
