Abstract

A safe production of sodium nitro-1,3-propanediol from a reaction solution of nitromethane and paraformaldehyde in methanol by addition of sodium methylate is achieved by evaporative cooling of the methanol; it being possible to maintain reaction temperatures of 35.degree. C. to 50.degree. C.
