摘要:一种改进的二烷基二硫代磷inic酸生产工艺,包括通过以下方式对纯化的二烷基磷inic酸进行硫化:在自由基引发剂的存在下,使亚磷onic酸或其盐与α-烯烃以化学计量过量的比例反应,形成包含单烷基磷inic酸和二烷基磷inic酸的反应产物;向反应产物中加入足够的水性碱,以形成磷inic酸的盐,并建立水相和有机相,其中单烷基磷inic酸溶于水相;将有机相从水相中分离;酸化有机相并从有机相中去除烯烃;隔离纯化的二烷基磷inic酸产物;并对纯化的二烷基磷inic酸产物进行硫化,以形成二烷基二硫代磷inic酸.本发明还提供了一种制备纯化的二烷基硫代磷onic氯化物的方法,以及一种制备纯化的二烷基单硫代磷onic酸的方法.
