二苄基二硫代氨基甲酸锌制备及其光谱分析

采用一步法制备二苄基二硫代氨基甲酸锌(ZBDC)，通过FTIR，UV-Vis，XRD和TG-DSC对其进行检测和表征，揭示出ZBDC的微观结构和内在规律性。FTIR揭示了ZBDC分子内部各元素之间的化学键键型，确定最终产物为ZBDC。UV-Vis检测出ZBDC在209.8和266.1 nm有二个吸收峰，分别由n→σ*和π→π*的电子跃迁产生的，为企业ZBDC产品质量检测，推测ZBDC的结构提供实验依据。XRD从晶胞参数、晶面指数等晶体学数据，变换出ZBDC晶体微观结构，完成ZBDC物相组成和结构的定性鉴定。TG-TG-DSC检测出ZBDC的质量变化与热效应两种信息，在194.5，361.1和433.5 ℃存在三个吸热峰，分别为相变峰和分解峰。ZBDC分解温度偏高，为采用硫化仪研究ZBDC的橡胶硫化性能提供参考。

Study on the Preparation of Zinc Dibenzyl Dithiocarbamate and Its Spectral Analysis

In the study, Zinc dibenzyl dithiocarbamate (ZBDC) was synthesized with one-step method. ZBDC was detected and characterized with FTIR，UV-Vis，XRD，TG-DSC. Its micro-structure and intrinsic regularity were revealed. Chemical bond types into ZBDC molecule were revealed with FTIR. The final product was determined as ZBDC. Two absorption peaks were detected with UV-Vis at 209.8，266.1 nm respectively, due to n→σ*, π→π* electronic transitions. It could provide experimental basis for enterprise to test ZBDC product quality and speculate its structure. ZBDC phase composition and structure were revealed through crystallographic data from XRD detecting such as cell parameters, crystal face index. The phase composition and qualitative identification of ZBDC structure were completed. Two kinds of information were detected with TG-DSC as quality change and thermal effect. There were three absorption peaks of 194.5，361.1，433.5 ℃, due to transition peak and decomposition phase of ZBDC respectively. The decomposition temperature of ZBDC was very high. It could provided reference for research on rubber vulcanizing properties with ZBDC on rubber vulcanizing machine.
