Amides of phosphorus-containing acids are reacted with sulphenyl halides to give phosphorus-containing acid amides in which one or more of the nitrogen atoms carries the appropriate substitutent attached through a sulphur atom. These substituted amides are inhibitors of premature vulcanisation in rubbers. The most effective compounds are arylamides substituted by secondary alkylthio groups.
含磷酸酰胺与亚磺酰卤化物反应,可得到含磷酸酰胺,其中一个或多个氮原子通过硫原子连接适当的取代基。这些取代酰胺是橡胶预热硫化的抑制剂。最有效的化合物是被次烷硫基取代的芳基酰胺。
