METHOD OF STABILIZING ALDEHYDES

摘要

The present method makes it possible to stabilize aliphatic C3-C14-aldehydes against polymerization and autocondensation. It comprises the addition of alkaline substances to the aldehydes wherein the alkaline substances used are alkali metal hydroxides, alkaline earth metal hydroxides, alkali metal carbonates, alkaline earth metal carbonates or alkaline earth metal carboxylates and are added to the aldehyde to be stabilized in amounts of 0.05-20 ppm, based on the aldehyde.
