Abstract
A process for producing and refining trisubstituted glycol monoesters, e.g., 2,2,4-trimethyl-1,3-pentanediol monoester. The improvement resides in immediately distilling the crude condensation product mixture as it leaves the reactor before it has cooled or had any contact with added water.
