Participants

Reaction Steps

104 g (1.6 mols) of potassium cyanide are dissolved in 100 ml of water. 160 g (1.6 mols) of a 30% strength formaldehyde solution are introduced at between 5° and 10° C. The mixture is stirred for 30 minutes. 212 g (1.2 mols) of benzenesulphonyl chloride are introduced dropwise at a temperature of between 10° and 20° C. The mixture is stirred at this temperature for 6 hours. The product is extracted with benzene. The benzene is washed with water. The benzene phase is decanted. Traces of water are removed by distilling the C6H6.H2O azeotrope. The benzene is evaporated to dryness and the residue is distilled in vacuo.
