  摘要：

  提供了一种生产环脲的方法。该方法包括在存在脱氯化剂的情况下，使式（II）R-HN-R'-NH-R（II）表示的二胺与光气发生反应，其中R代表氢原子或较低的烷基基团，R'代表二甲基基团、较低的烷基基团取代的二甲基基团、三亚甲基基团、较低的烷基基团取代的三亚甲基基团、四亚甲基基团、较低的烷基基团取代的四亚甲基基团，但排除了R代表氢原子且R'代表二甲基基团、R代表氢原子且R'代表较低的烷基基团取代的二甲基基团以及R代表甲基基团且R'代表二甲基基团的情况。在该过程中，首先将二胺转化为其盐酸盐，然后将盐酸盐与光气在水溶剂中反应，同时通过所述的脱氯化剂将反应液的pH维持在5.0至8.0范围内，以获得式（I）所表示的环脲，其中R和R'如上所定义。
