Applications

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.

Notes

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.
