酸性树脂催化合成二苯硫脲
Catalytic Synthesis of N,N’ -Diphenyl Thiourea Using Acidic Resin as Catalyst
【摘要】 探讨了合成二苯硫脲的新方法。以酸性树脂作催化剂在回流温度下使苯胺与CS2 反应 6h ,二苯硫脲的收率达 82 7% ,选择性为 10 0 %。提出了酸性树脂催化苯胺与CS2 反应的可能机理 ,并对二苯硫脲的分解进行了研究。
【Abstract】 A new method to synthesize N,N’ -diphenyl thiourea (DPTU) from aniline and CS 2 was developed in the presence of acidic resin as catalyst under reflux temperature for 6 h with the yield of 82.7% and the selectivity of 100%. The related reaction mechanism was proposed and DPTU decomposition was examined.
