Process for the production of alkylene glycols

A process for the production of alkylene glycol which comprises contacting water and an alkylene oxide in the presence of a heterogeneous catalyst comprising a partially amine-neutralized sulfonic acid resin wherein the mole ratio of alkylene oxide to water ranges from about 2 to 5, the temperature of reaction ranges from about 100.degree. to about 125.degree. C. and the reaction pressure ranges from about 200 to 400 psi.

A process for the production of alkylene glycol which comprises contacting water and an alkylene oxide in the presence of a heterogeneous catalyst comprising a partially amine neutralized styrene-divinylbenzene copolymer having pendant sulfonic acid groups wherein the mole ratio of alkylene oxide to water ranges from about 2 to about 10, the temperature of reaction ranges from about 100.degree. to about 200.degree. C. and the reaction pressure ranges from about 200 to 400 psi.
