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 alumina or halided alumina as catalyst and recovering the product. When said aromatic compound is phenol, said olefin is isobutylene, and said catalyst is fluorided or chlorided alumina, 2,4-di-t-butylphenol is formed with superior selectivity.
