Abstract:In the study, rubber accelerator 3-methylthiazolidine-2-thione (MTT) was synthesized by one-step method firstly. MTT was detected and characterized by XRD, FTIR, TG-DSC. The micro-structure and intrinsic regularity were revealed. Chemical bond types into MTT molecule were revealed by FTIR. MTT 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 MTT structure were completed. Two kinds of information were detected by TG-DSC as quality change and thermal effect. MTT phase transition and decomposition temperature were 76.3 and 306.9 ℃ respectively. The decomposition temperature of MTT was very high. It could provided reference with research on rubber vulcanizing properties by MTT on rubber vulcanizing machine. This study can provide the basis experimental data on the enterprises to designate the working standard tracing detection of MTT industrialized production. Performance index of MTT was judged.
