Process for the preparation of p-toluenesulfochloride |
| abstract |
Improved process for the preparation of p-toluenesulfochloride, wherein for each mol of toluene about 1 - 2 mols of chlorosulfonic acid and about 0.1 - 1 mol of an alkali metal-, alkaline-earth metal- or ammonium salt are placed in a reaction vessel, Toluene is added thereto and after reacting at 60* - 90* C the mixture is cooled to about 30* - 40* C, a further amount of chlorosulfonic acid (at least 1 mol per each mol of toluene) is added and the reaction mixture is treated to form ptoluenesulfochloride. In comparison with known processes the instant process has the great advantage that the ptoluenesulfochloride is obtained in a much higher yield. |
