  • Process for manufacturing haloaryl compounds from mixtures of isomers of dihalodiarylsulfone
    Patent number: 9212111
    Abstract: A process for the manufacture of a haloaryl compound which comprises contacting a mixture of dihalodiarylsulfone isomers [mixture (M)] with sulfuric acid to provide a mixture of haloarylsulfonic acid isomers [mixture (M1)] and reacting mixture (M1) in the presence of water. The process is independent on the manufacturing process of mixture (M) and is advantageous in that the obtained haloaryl compound can be recycled to the first step of a dihalodiarylsulfone manufacturing process.
    Type: Grant
    Filed: December 11, 2012
    Date of Patent: December 15, 2015
