联产三氯氧磷和氯化亚砜新工艺的研究

Study on the Technology of United Production of POCl_(3)and SOCl_(2)

以硫酰氯和三氯化磷为原料，采用间歇式一步转化法联产三氯氧磷和氯化亚砜，在 45～ 65℃，常压条件下 7～ 8 h内，将三氯化磷滴加入硫酰氯中进行反应，并保温 0. 5 h，可分别得到 98. 5％的氯化亚砜， 99％以上的三氯氧磷，收率均在 98％以上。

By making use of intermittent process, POCl3and SOCl2 were unitedly produced with POCl3 and SOCl2 as raw materials, with one－ step conversion method.The reaction was finished in 7－ 8 hours by dripping PCl3 into SO2Cl2 at 45－ 65℃ and maintaining the above temperature for 30 minutes, the fineness of POCl3 and SOCl2 can respectively reach 98.5％ and 99.0％ , and their direct production ratio all get to above 98％ .
