2,4-Dimethyl-6-tert-butylphenol is theorganic compound with the formula Me2(tert-Bu)C6H2OH (Me =methyl,tert-Bu = tertiary butyl). It is a colorless oil that is classified as analkylatedphenol.[1]
It is used as anantioxidant, e.g. to prevent gumming infuels, and as an ultraviolet stabilizer. It is used injet fuels,gasolines, andavgas.
It is prepared by alkylation of xylenol withisobutylene. This alkylation provides a means to separate 2,4-xylenol from 2,5-xylenol since 2,4-dimethyl-6-tert-butylphenol is insoluble in 10% NaOH but 2,5-dimethyl-6-tert-butylphenol is soluble. Subsequent to separation, the tert-butyl group can be removed in strong acid.[1]
One of its trade names isTopanol A. It is found in antioxidant mixtures AO-30, AO-31, AO-32, IONOL K72, IONOL K78, IONOL K98, and others.
