White powder/granule. The density is 1.32. A little bitter, flammability, almost no poison. Soluble in alcohol, acetone, diethylether, cyclohexanone, tetrohydrofuran, partly soluble in all PVC platicizers, insoluble in water and CS2. Soluble in alkali solutions and precipitation from acid solution.
Medium-speed vulcanization accelerator. Synergises with sulfur donor to boost vulcanization when used in NR, SBR. Need ZnO to be effective. Used as secondary accelerator in CR & EPDM vulcanization system. Used in latex products, cables and general industrial products. Its critical temperature is 80. also could b used as raw materials for pharmaceutical and dye and the best reagent for Os and Rh.
