Applicazioni

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.

Note

Light-sensitive. Keep the container tightly closed in a cool, dry and well-ventilated place. Incompatible with acid chlorides, acid anhydrides, oxidizing agents, bases, brass, copper and copper alloys.

Letteratura

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).
