ABSTRACT:
A process for introducing a plurality of alkyl groups into the aromatic ring of a hydroxy-substituted aromatic compound comprises contacting said aromatic compound with an olefin in the presence of a lithiated alumina as catalyst and recovering the product. When said aromatic compound is phenol, said olefin is iso-butylene, and said catalyst is lithiated alumina, 2,4-di-t-butylphenol is formed with superior selectivity.
