Molecular formula : C14H8N2S4
MW : 332.47
CAS No. :120-78-5
nature : precipitation from benzene light yellow crystalline needle. The temperature of 180 ° C, there were also reports of 186 ° C and relative density of 1.50 (20 / 4 ° C). Do not dissolve in water, 25 ° C in the following substances solubility (g/100ml) : <0.2 ethanol, acetone <0.5, <0.5 benzene, carbon tetrachloride <0.2, ether <0. 2. Slightly bitter, no foul.
Preparation : to promote M as raw material, sodium nitrite as oxidizer, in acid medium-income generated from air oxidation.
purposes : thiazoles vulcanization accelerator. For natural rubber, synthetic rubber and plastic regeneration, the use and promotion of M similar, but higher critical temperature vulcanized (130 ° C). It is commonly used in the vulcanization accelerator, widely used in tires, hoses, rubber mats, tarpaulins, unveiled silk goods rubber hose, wires, cables, rubber and other non-food use of rubber products. The goods toxicity, but can stimulate the mucous membrane and skin.
