Process for the production of arylsulfonyl halides |
| abstract |
There is disclosed a process for the production of arylsulfonyl halides, e.g., benzenesulfonyl chloride. The disclosed process adds a phosphorus-containing additive, e.g., phosphorous acid, before the reaction of an arylsulfonic acid with a sulfur halide and a halogen. The phosphorus-containing additive reduces the thermal instability of the residue remaining after distillation of the arylsulfonyl halide. |
