Conditions

Temperature
110 °C

Procedure

110 g of o-xylene, 176 g of benzenesulphonyl chloride and 0.16 g of iron(III) chloride are brought together at room temperature and the mixture is heated at 110° C. in the course of 2 hours. When the evolution of HCl has ended, the mixture is heated to 140° C. and the product is discharged onto a metal sheet. On cooling, the melt solidifies to a colourless mass. Yield: 243 g.
