Abstract
In the process for catalytically reacting olefin and oxygen to provide glycol or a mixture of glycol and glycol ester, higher rates of reaction and/or higher selectivities for the desired product(s) are obtained employing as catalyst, a composition comprising a mixture of molecular iodine and hydrobromic acid; hydriodic acid and hydrobromic acid; or, at least one oxide of antimony, bismuth or tellurium in admixture with at least one member of the group consisting of hydriodic acid; molecular iodine; hydriodic acid and molecular iodine; molecular iodine and hydrobromic acid; and, hydriodic acid and hydrobromic acid in a water or water-carboxylic acid reaction medium.
