Abstract

A product containing both pentaerythritol and dipentaerythritol is obtained by reacting together formaldehyde, acetaldehyde and a base by first forming a reaction mixture in which the process is substantially complete and then adding further quantities of the reactants at such a rate that the concentrations of free aldehydes in the mixture do not increase substantially. The formaldehyde is used as an aqueous solution of 5-12% by weight concentration. Preferably the molar ratio of formaldehyde to acetaldehyde is from 4:1 to 10:1 and the base used is sodium or potassium hydroxide. The preferred temperature range for carrying out the process is 50-90 DEG C.
