Abstract：In the study, zinc O,O,O’,O’-tetrabutyl bis(phosphorodithioate) (ZBPD) was synthesized with two-step method firstly. ZBPD was detected and characterized with UV-vis, FT-IR andTG-DSC. Its micro-structure and intrinsic regularity were revealed. Two absorption peaks were detected with UV-Vis at 212.0 and 227.0 nm respectively caused by n→σ*, π→π* electron transition. The intensity of peaks was changed with the regularity with different ZBPD concentration. It could provide the basic data with the enterprise of ZBPD product quality inspection. Chemical bond types into ZBPD molecule were revealed by FT-IR. Two kinds of information were detected by TG-DSC as quality change and thermal effect. The DSC curve of ZBPD was very complex. There were a wide absorption peak of 84.3 ℃, four exothermic peaks of 245.0, 344.3, 476.1, 344.3 ℃, due to the molecular structure of ZBPD and small amounts of impurities. The decomposition temperature of ZBPD was very high. It could provided reference with research on rubber vulcanizing properties by ZBPD on rubber vulcanizing machine. This study could provide the basis experimental data on the enterprises to designate the working standard tracing detection of ZBPD industrialized production. Performance index of ZBPD was judged. The project of ZBPD industry standard could be declared by the enterprises, written a draft standard.
