Abstract
Ammonium or amine salts of dialkyl monothiophosphates are obtained by the action of sulphur and ammonia or an organic amine on a dialkylphosphite. In the example diethyl phosphite dissolved in ethyl alcohol is treated with powdered roll sulphur while ammonia is passed in, heating to 50 DEG C., to give ammonium diethylmonophosphate, separating on cooling. Methylamine and dimethylamine are suitable amines.
