Publication number: 20050059843Abstract: A method for preparing hydroxyaromatic compounds brominated in the para-position, such as p-bromophenol, is disclosed. The method yields overall high process selectivity through isomeric equilibration and separation of the brominated products, thereby eliminating the need for high para selectivity in the products of catalytic oxybromination reactions of hydroxyaromatic compounds using oxygen, a bromine source, and an acidic medium in the presence of a metal catalyst. Furthermore, the invention provides an efficient method for recycling the metal catalyst, as well as reagents used in the bromination, to further reactions.Type: ApplicationFiled: September 17, 2003Publication date: March 17, 2005Applicant: General Electric CompanyInventors: Eric Pressman, Jonathan Male, Ryan Mills, John Ofori
