2,6-Di-tert-butyl-4-methylphenol is used as an antioxidant for cosmetics, vitamins, pharmaceuticals, rubber, oils and fats. It is used as a fuel additive in the petroleum industry and also used in hydraulic fluids, turbine and gear oils and jet fuels. It acts as a stabilizer in diethyl ether, tetrahydrofuran and other laboratory chemicals to prevent peroxide formation. It is effectively involved as a polymerization inhibitor in the process of oxidation of allyl alcohol to glycerine. It is utilized in the synthesis of organoaluminum compound, methylaluminum bis(2,6-di-tert-butyl-4-alkylphenoxide.
Radical inhibitor and antioxidant, readily soluble in nonpolar media. Finds widespread use in the inhibition of peroxide formation in ether solvents and also as a preservative/ antioxidant for unsaturated oils and fats in the food, synthetic rubber and paint industries.
Source of t-butyl group in aromatic substitution reactions. For reviews of the use of t-butyl as a positional protecting group for aromatic substitution reactions, readily removable with, e.g. AlCl 3 in toluene, see: Org. Prep. Proced. Int., 8, 51 (1976); Synthesis, 921 (1979)./n
