| titleOfInvention | Preparation of aromatic sulfohalides |
| abstract | ABSTRACT OF THE DISCLOSURE: A process for the preparation of aromatic sulfohalides by reacting an aqueous solution t containing a hydrogen halide, of an aromatic diazonium halide with sulfur dioxide, wherein a) the aqueous solution, containing the hydrogen halide, of a diazonium salt which is derived from the corresponding aromatic amine and the halogen of the desired sulfohalide is reacted with sulfur dioxide in the presence of an organic solvent which is immiscible or only partially miscible with water, is substantially inert to aqueous acids and SO2 and has adequate solvent power for SO2 and for the sulphochloride formed, b) the diazonium salt is decomposed, simulta-neously or subsequently, by means of a catalyst for diazonium salt decomposition and c) the resulting reaction mixture, or the organic phase thereof after removal of the aqueous phase, is treated with an oxidizing agent. |
