In the study,rubber accelerator Zinc diethyldithiocarbamate (EZ) was synthesized firstly.Complex EZ of single crystal was cultivated by solvent evaporation method.EZ was detected and characterized by XRD single crystal diffraction,FTIR and TG-DSC.The micro-structure and intrinsic regularity were revealed.Its highly efficient performance of rubber vulcanization promotion was decided due to its orientation structure?and high order.The result of TG-DSC showed that complex EZ was possessed with a little CS2.The chemical bond types in EZ were revealed by FTIR,the same as single crystal?diffraction testing by different way.The decomposition temperature of EZ was very high.It could provided reference with research on rubber vulcanizing properties by EZ on rubber vulcanizing machine.This study can help the enterprises to designate the working standard tracing detection of EZ industrialized production.Performance index of EZ was judged.The project of EZ industry standard can be declared by the enterprises,written a draft standard on the basis experimental data.
