[General Description]

White or light gray to tan powder.
[Reactivity Profile]

4,4'-THIOBIS(6-TERT-BUTYL-M-CRESOL)(96-69-5) may be sensitive to light.
[Air & Water Reactions]

Sensitive to base hydrolysis and may spontaneously oxidize in solution. . Insoluble in water.
[Potential Exposure]

This material is used as an antioxidant in the plastics and rubber industries; in Neoprene and other synthetic rubbers; in polyethylene and polypropylene.
[Fire Hazard]

This chemical is combustible.
[First aid]

Skin Contact: Flood all areas of body that have contacted the substance with water. Don’t wait to remove contaminated clothing; do it under the water stream. Use soap to help assure removal. Isolate contaminated clothing when removed to prevent contact by others. Eye Contact: Remove any contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at least 2030 minutes. Seek medical attention. Inhalation: Leave contaminated area immediately; breathefresh air. Proper respiratory protection must be supplied to any rescuers. IF coughing, difficult breathing or any other symptoms develop, seek medical attention at once, even if symptoms develop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk to dilute the substance. Assure that the person’s airway is unobstructed and contact hospital or poison center immediately for advice on whether or not to induce vomiting.
[Incompatibilities]

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. May evolve explosive hydrogen sulfide upon contact with moisture or acids.
[Description]

4,4'-Thiobis(6-tert-butyl-m-cresol) (Antioxidant 300), melting point 161-163℃, white powder, low volatility, low toxicity; soluble in organic solvents such as benzene, toluene, acetone, methanol, ethanol, carbon tetrachloride, slightly soluble in petroleum solvents, insoluble in water, is a non-polluting, high-efficiency phenolic antioxidant with low volatility, high antioxidant efficiency, good thermal stability and weather resistance, and little effect on the electrical properties of the product. It also has a synergistic effect when used with carbon black and octadecyl alcohol. It can be used as an antioxidant for polypropylene, ABS, polystyrene, polyphthalamide, polyurethane, etc., and is suitable for white, bright-colored and transparent products. It has very low toxicity and is allowed to be used in plastic products that come into contact with food in many countries.
[Chemical Properties]

4,40-Thiobis(6-tert-butyl-m-cresol) is a light gray to tan powder. Aromatic odor.
[Chemical Properties]

white to almost white crystals or crystalline
[Hazard]

Toxic by inhalation. Upper respiratory tract irritant. Questionable carcinogen.
[Health Hazard]

4,4'-Thiobis(6-tert-butyl-mcresol) (TBBC) is of low systemic toxicity in animals; allergic contact dermatitis has been reported in humans.
[Flammability and Explosibility]

Nonflammable(100%)
[Synthesis]

2-tert-butyl-5-methylphenol (164.2, 1.0mol), silver nitrate (169.9, 1.0mol), iodine (253.8g, 1.0mol) and dichloromethane 0.7L is added to the reactor, stirred at room temperature under light-proof conditions, and the colour of iodine gradually disappears, accompanied by the generation of silver iodide. After 30 min, the generated silver iodide is filtered and recovered, and the filtrate is washed with 1.1L water and recycled for washing Water. After the organic phase is dried with industrial anhydrous magnesium sulfate, Cu (8.2g), thiourea (38.1g, 0.5mol) and triethylamine 200g (about 273ml) are added inside and then reacted for 4 hours under reflux. After the reaction terminates, it is naturally cooled to room temperature, and the Cu catalyst is filtered and recovered; then water is added for dilution and washing, and after separating the aqueous phase, the organic phase is added with water again, and the pH is adjusted to 6-7 with phosphoric acid, and the aqueous phase is separated after standing. The organic phase was washed with saturated sodium chloride aqueous solution and water, respectively, dried with industrial magnesium sulfate, distilled under reduced pressure, and dichloromethane was recovered, then recrystallized with ethanol. 159.5 g of 4,4′-thiobis(6-tert-butyl-3-methylphenol) was obtained.
[Carcinogenicity]

TBBC was not mutagenic in Salmonella typhimurium strains with or without metabolic activation. In Chinese hamster ovary cells, TBBC induced an increase in sister chromatid exchanges but there were no increases in chromosomal aberrations.
