Abstract:High quality O,O-dimethylthiophosphoryl chloride was systhesized by alcoholysis and chlorination using phosphorus pentasulfide as starting material. The advantages include no alkali hydrolysis, less chlorine flux, less waste water and high product content. Under the optimum conditions, the target compound was obtained with purity of 99%, and the total yield is 80%. This method is suitable for industrial production.
Key words:phosphorus pentasulfide; O,O-dimethylthiophosphoryl chloride; catalytic; synthesis
