    摘要: The present invention relates to a process for preparation of Echothiophate Iodide (I). Echothiophate Iodide (I) obtained by the process of the present invention is obtained as new crystalline form designated as Form-SET. The process for preparation of Echothiophate Iodide (I) according to present invention is an ecofriendly process that avoids the use of hazardous solvent systems and provides Echothiophate Iodide (I) of high purity. Pharmaceutical composition of the said crystalline Form-SET of Echothiophate Iodide (I) of high purity is useful in the treatment of ocular disorders like Glaucoma.

    摘要: The manufacture of trialkyltrithiophosphites by reacting an excess of an alkyl mercaptan with phosphorous trihalide and scrubbing of noncondensible reactor off-gases with strong caustic solution, continuing the scrubbing until the strong caustic solution becomes spent though still mildly alkaline when the alkyl mercaptan separates into a separate phase. The mercaptans are separated to recycle. The trialkyltrithiophosphite can be oxidized to trialkyltriphosphorothioate with further stripping and recovery of remaining mercaptans.
