Abstract
This invention relates to an improved method for the catalyzed condensation of aldehydes in the liquid phase to form 1,3-glycol monoesters utilizing tin metal or a tin oxide catalyst. Condensation can be visualized as an aldol condensation followed by a Tischenko reaction between the aldol and a third molecule of aldehyde. In its simplest form the condensation can be illustrated by the following general formula ##STR1## R or R.sup.1 =Hydrogen or alkyl group of 1 to 20 carbon atoms or aromatic groups. R and R.sup.1 can also be part of a cyclic system.
