    摘要: The present invention provides a method for making O,S-dimethyl phosphoramidothioate. In accordance with this process, O,O-dimethyl phosphoramidothioate is isomerized in the presence of dimethyl sulfate to form a reaction mixture; the reaction mixture is then passed through a wiped film evaporator at a temperature of from about 55.degree. C. to about 120.degree. C. and a pressure of from about 3 to about 10 mm Hg, with the distillate containing O,S-dimethyl phosphoramidothioate, unreacted O,O-dimethyl phosphoramidothioate and by-products, and the residue containing O,S-dimethyl phosphoramidothioate in an amount greater than the amount of O,S-dimethyl phosphoramidothioate contained in the reaction mixture prior to distillation.

    摘要: The present invention relates to an integrated process for synthesizing dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate and a process for impregnating the dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate on to inert carrier granules. The process involves adding dimethyl phosphite to a reaction mixture containing chloral under anhydrous, inert conditions. The molar ratio of chloral to dimethyl phosphite used in the reaction mixture is from about 1.0:1.0 to about 1.1:1.0. The impregnation process involves transferring molten dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate into a process vessel and discharging weighed aliquots into a formulation vessel to form a granular product containing dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate.
