| 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. |
