[Study on the Preparation of N-Tert-Butylbenzothiazole-2-Sulphenamide and Its Spectral Analysis]

In the study, N-tert-butylbenzothiazole-2-sulphenamide (TBBS) was synthesized with one-step method with hydrogen peroxide as the oxidant. TBBS was detected and characterized with FTIR，UV-Vis，XRD and TG-DSC. Its micro-structure and intrinsic regularity were revealed. Chemical bond types into TBBS molecule were revealed with FTIR. The final product was determined TBBS. Three absorption peaks were detected by UV-Vis at 228.3，281.5，298.3 nm respectively, due to n→σ*，π→π*，n→π* electronic transitions. It could provide experimental basis with enterprise to test TBBS product quality and speculate its structure. The phase composition and structure of TBBS were revealed by crystallographic data from XRD detecting such as cell parameters, crystal face index. The phase composition and qualitative identification of TBBS structure were completed. Two kinds of information were detected by TG-DSC as quality change and thermal effect. The DSC curve of TBBS was very complex. There were a small absorption peak of 53.3 ℃ as a small amount of tert-butylamine containing in TBBS was oxidized. Three exothermic peaks of 117.4，269.2，373.7 ℃, due to transition peak and decomposition phase of TBBS respectively. The decomposition temperature of TBBS was very high. It could provide reference for research on rubber vulcanizing properties by TBBS on rubber vulcanizing machine. This study could provide the basis experimental data on the enterprises to designate the working standard tracing detection of TBBS industrialized production. The performance index of TBBS was judged. The project of TBBS industry standard could be declared by the enterprises, written a draft standard.
