Abstract

The monoformals and diformals of pentaerythritol and dipentaerythritol are produced by reacting these alcohols with paraformaldehyde at a temperature of from about 90 to 150 DEG C in the present of an acid substance as catalyst. The pentaerythritol and the dipentaerythritol as well the paraformaldehyde are used in the form of solid substances and the reaction is carried out in the absence of a solvent.
