It can further reacts with diphenylguanidine to form a stable, neutral, violet-red 1:2:1 ternary ionic-associate complex.
它可与二苯胍进一步反应形成电中性的稳定紫红色1∶2∶1三元离子缔合络合物。

Diphenylguanidine has been prepared by using of Fe2 O3 as catalyst and 70% ethanol as solvent, and simultaneously the by - product H2S is used to prepare thiourea.
本文提出了在70%乙醇溶剂中以氧化铁作为触煤合成二苯胍，同时回收副产硫化氢合成硫脲的联合制备方法。
