Latest Patents

One of Rew's latest patents outlines a synthetic method for producing glycol diesters through the reaction of glycol monoesters and linear aliphatic carboxylic acids. This innovative method employs a Lewis acid type catalyst to facilitate the reaction. The process involves introducing the glycol monoester, along with the linear aliphatic carboxylic acid and the Lewis acid catalyst, into a reactor. As the reaction proceeds, it generates both reaction products and water. An excess of the linear aliphatic carboxylic acid creates an azeotrope with water, which is then directed to a condenser via a distillation column. The resultant mixture is separated into an organic layer and an aqueous layer in an oil-water separator. The organic layer is cycled back to the distillation column, while water is removed from the aqueous layer. This method's reactive distillation technique allows for the rapid removal of water, significantly reducing reaction time and maximizing the yield of glycol diester.
