Abstract
In the preparation of glycol esters by the liquid phase reaction of an olefin, molecular oxygen, and a carboxylic acid in the presence of a catalyst system comprising a variable valent cation in association with bromine, chlorine, a bromine-containing compound or a chlorine-containing compound, improved reaction rate and product selectively are achieved by carrying out the reaction in a vertical reaction zone communicating with at least one zone for movement of liquid from the top of the vertical reaction zone to the bottom of said reaction zone, and providing gaseous and liquid feeds in predetermined relationships and providing predetermined vertical superficial liquid velocities.
