以对苯二甲酰异硫氰酸酯和邻苯二胺为原料通过界面缩聚法合成了聚硫脲缓释微胶囊。

Novel controlled releasing polythiourea microcapsules were prepared from terephthaloyl diisothiocyanate and o-phenylenediamine by interfacial polycondensation.

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。

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.
