ABSTRACT:
An improvement in the process for making a dialkyl phosphorochloridothioate from P.sub.2 S.sub.5, alkyl alcohol and chlorine in which the desired product is separated from the reaction mixture by distillation, leaving an unstable, acidic residue, wherein the residue is stabilized and neutralized by reaction with an organic base, thereby enhancing the value of the residue while avoiding potential environmental damage caused by disposal of the residue.
