PROCESS FOR THE PRODUCTION OF A SULFONE MONOMER

The present invention provides an economic and environmentally friendly method for the preparation of polymer grade 4,4'-dichlorodiphenyl sulfone which is substantially free of 2,4' and 3,4'-isomers of dichlorodiphenyl sulfone with yield of over 90%, with substantially reduced reaction times without the use of impregnated catalysts. Further no toxic byproducts such as dimethyl pyrosulfate are formed thereby reducing the load on effluent treatment with the added advantage of substantially recycling the reactants and byproducts. Further the present invention discloses a process is disclosed in which isomeric mixture of 4,4'-, 3,4'-, and 2,4'-dichlorodiphenyl sulfone produced during the preparation of 4,4'-dichlorodiphenyl sulfone is converted to value added products such as diphenyl sulfone, 2,4'- dihydroxydiphenyl sulfone, 4,4'-dihydroxydiphenyl sulfone and 2-aminodiphenyl sulfone.

Polystyrene supported Al(OTf)3: A stable, efficient, selective, and reusable catalyst for sulfonylation of arenes with sulfonic acids

Cross-linked polystyrene supported aluminium triflate (Ps-Al(OTf) 3) was found to be an efficient and chemoselective heterogeneous Lewis acid catalyst for the direct conversion of arenes to sulfones using sulfonic acids as sulfonylating agents. The solid acid catalyst is stable (as a bench top catalyst) and can be easily recovered and reused without appreciable change in its efficiency.

Method for acylation or sulphonylation of an aromatic compound

The present invention relates to a process for the acylation or sulphonylation of an aromatic compound. More particularly, the invention relates to a process for the acylation or sulphonylation of an activated or deactivated aromatic compound. The invention is applied to the preparation of aromatic ketones or sulphones. The process for the acylation or sulphonylation of an aromatic compound which consists in reacting at least one aromatic compound with an acylating or sulphonylating agent, in the presence of a Friedel-Crafts catalyst is characterized in that the acylation or sulphonylation reaction is carried out in liquid phase under microwave irradiation.
