以双氧水为氧化剂, 采用二步法合成出了二硫化四苄基秋兰姆(TBzDT), 通过FTIR, XRD, TG-DTA对其进行检测, 揭示了TBzDT的微观结构。 FTIR从化学键角度解析了TBzDT元素之间键型, XRD从晶胞参数、 晶面指数等晶体学数据, 揭示出TBzDT晶体微观结构, 完成了TBzDT物相组成和结构的定性鉴定。 TG-DTA检测出了TBzDT的质量变化与热效应两种信息, TBzDT的相变和分解温度分别为142.5, 200.9 ℃, TBzDT的分解温度偏高, 为采用硫化仪研究TBzDT的橡胶硫化性能提供参考。 FTIR和TG-DTA从不同侧面揭示出样品TBzDT 中蕴含少量的SC2。

In the study, rubber accelerator tetrabenzylthiuramdisulfide (TBzDT) was synthesized with two-step method with hydrogen peroxide as oxidant firstly. TBzDT was detected and characterized with XRD, FT-IR, TG-DTA. Its micro-structure was revealed. Chemical bond types into TBzDT molecule were revealed with FT-IR. TBzDT phase composition and structure were given by crystallographic data from XRD detecting such as cell parameters, crystal face index. The phase composition and qualitative identification of TBzDT structure were completed. Two kinds of information were detected with TG-DTA as to quality change and thermal effect. TBzDT phase transition and decomposition temperature were 142.5, 200.9 ℃ respectively. The decomposition temperature of TBzDT was relevtively high. It could provided reference with research on rubber vulcanizing properties by TBzDT on rubber vulcanizing machine. A little SC2 contained into TBzDT was revealed by FTIR, TG-DTA from different sides.
