Amides of phosphorus-containing thioacids are reacted with sulphenyl halides to give phosphorus-containing thioacid amides in which one or more of the nitrogen atoms carries a substituent attached through a sulphur atom. These substituted amides are inhibitors of premature vulcanisation in rubbers. The most effective compounds carry a secondary alkylthio or cycloalkylthio on each nitrogen atom.
含磷硫酸酰胺与硫酰卤素反应,可生成含磷硫酸酰胺,其中一个或多个氮原子通过硫原子连接带有取代基。这些取代酰胺可作为橡胶预热硫化的抑制剂。其中,两个氮原子上带有次烷硫基或环烷硫基的化合物最为有效。
