Description of key information

According to the Ullmanns encyclopedia (2012), formaldehyde is not stable in polar solvents such as alcohols and amines, as it undergoes reaction with these compounds.

Additional information

Polar solvents, such as alcohols, amines or acids, either catalyze the polymerization of formaldehyde or react with it to form methylol compounds or methylene derivatives.
