Preparation and microstructure analysis of tetrabenzylthiuram disulfide by catalytic oxidation method
In this study,a two-step method was used to obtain the ultra fast rubber vulcanization accelerator tetrabenzylthiuram disulfide(TBzTD)with high melting point and quality using hydrogen peroxide as oxidant,98％sulfuric acid as catalyst,water as the solvent,and n(carbon disulfide)∶n(sodium hydroxide)∶n(hydrogen peroxide)∶n(dibenzylamine)=1.05∶1.0∶1.2∶1.0.This process route has low investment,low energy consumption,strong reaction controllability,and high yield and purity of the target product.It is an environmentally friendly and clean production process with broad industrial application prospects.The target product TBzTD was detected and analyzed by FT-IR,UV-vis,HPLC,XRD,and 1HNMR to reveal its microstructure,providing basic experimental data for exploring its performance and application.
