[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.
