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%.

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827%，选择性为100%。

This mechanism can also reasonably explain the fact that only molecular ionic peak of phenyl iso-thiocyanate and naphthyl iso-thiocyanate was presented in the GC/ MS spectra of diphenylurea and diphenyl thiourea.

此机理同样能合理解释二苯脲和二萘硫脲的GC/MS谱图中只出现异氰酸苯酯和异硫氰酸萘酯分子离子峰的现象。

But the GC/ MS analysis showed that it is phenyl isocyanate. This may be due to neutral loss of aniline in the cleavage of diphenyl thiourea in GC/ MS analysis.

但用GC/MS分析该晶体为异硫氰酸苯酯，这可能是在GC/MS分析过程中二苯硫脲发生了中性丢失苯胺的缘故。

Under mild conditions, at room temperature and ambient atmosphere, diphenyl thiourea could be synthesized through the reaction of aniline and CS 2 over AlCl 3 catalyst with high yield and high selectivity.

常温常压下，用AlCl3作催化剂催化苯胺和CS2进行反应，可以高收率和高选择性地得到二苯硫脲。

However, identified by melting point, HPLC/ MS/ MS, FTIR, UV and 1H NMR analyses, the pure crystal should be diphenyl thiourea.

然而，用熔点测定、HPLC/MS/MS，FTIR，UV和1H NMR等手段对此晶体进行分析，确定其为二苯硫脲。
