Following is the molecular structure of Pentachlorothiophenol (133-49-3):

Pentachlorothiophenol (133-49-3) is natural rubber, neoprene, nitrile rubber, styrene-butadiene rubber and butyl rubber, and plastic refining accelerator, as well as with Synthetic rubber composition of the regeneration of the higher doses. Applicable to high temperature and low temperature plastic plastic refining refining, sulfur may terminate the role of plastic solution. The product toxicity, no pollution, no smell vulcanized rubber, the rubber physical properties and aging properties of no effect. The product with the zinc sulfate solution, the reaction of thiophenol five zinc chloride can be used as natural rubber plasticating accelerator, high, low use of technology showed a significant catalytic role, suitable for open mill and mixer. 5 Chloro thiophenol zinc vulcanizate physical properties, aging properties, as well as chlorine taste and so no effect can be used for light-colored products. The product of real material with mineral mixtures nearly equal weight, then adding a small amount of organic activator, that is composed of five chloro-thiophenol compound, also be used as natural rubber, polybutadiene rubber, isoamyl rubber, styrene-butadiene rubber, NBR rubber, neoprene, butyl rubber and other unsaturated bond-containing rubber peptizer, low temperatures can also have a good solution of the role of plastic. The role of a small amount of sulfur solution for termination of its plastic effects.

Manufacturing methd of Pentachlorothiophenol (133-49-3):Pentachlorothiophenol is formed by HCB reaction with sodium hydrosulfide, with dimethyl formamide and other organic solvents as solvent. Reaction of the five chlorine thiophenol in the reaction system and then with sodium hydrosulfide, resulting in five thiophenol sodium chloride and hydrogen sulfide. Then, hydrochloric acid 5 sodium chloride precipitates thiophenol thiophenol pentachlorophenol, and then filtering, washing, drying, that is to be finished five chlorine thiophenol.

Chlorophenol compounds are on The Community Right-To-Know List. Reported in EPA TSCA Inventory.

Poison by intraperitoneal route. Mildly toxic by ingestion. Severe eye irritant. When heated to decomposition it emits very toxic fumes of SO_x and Cl⁻.
