4-tert-Butylcatechol (TBC) is an organic chemical compound which is a derivative of catechol. It is added as a stabilizer and an inhibitor of polymerization to butadiene, styrene, vinyl acetate and other reactive monomer streams. It is 25 times better than hydroquinone at 60°C for polymerization inhibitory effect. Also used as a stabilizer in the manufacture of polyurethane foam. It also can be used as an antioxidant for synthetic rubber, polymers and oil derivatives. It can be used as purification agent for aminoformate catalysts. TBC is available in a form of a solid crystal and 85% solution in methanol or water.
1. Used as polymerization inhibitor of styrene, butadiene and other vinyl monomers, and as stabilizer of antioxidant and insecticide
2. Used as polymerization inhibitor and antioxidant
3. Used as high efficiency polymerization inhibitor and antioxidant; Used as a passivating agent for carbamate catalyst; Used as stabilizer of organic compounds
4-tert-butylcatechol (PTBC) is used as an antioxidant in fats, oils, and mineral oils, and as a stabilizer in polyester resins and polystyrene resins. A concentration of PTBC (up to 0.005%) can be found in paints, glues, thermal paper, lubricating oil, and mineral oil products.
4-tert-Butylcatechol is widely utilized as an inhibitor in polymerization of butadiene, styrene, vinyl acetate and other reactive monomers. It plays an important role in the synthesis of tungsten oxide nanoparticles by nonaqueous sol-gel process. It acts as a stabilizer in the manufacturing of polyurethane foam. It is employed as an antioxidant for synthetic rubber, polymers and oil derivatives. It is also utilized as a purification agent for aminoformate catalysts.
