Reaction Steps

A mixture of 3.7 g of hydroxylamine sulphate, 7 g of sodium acetate trihydrate, 17 g of acetic anhydride, 5 ml of acetic acid and 4.5 g of 2,6-dichlorobenzaldehyde was heated at reflux for 34 hours. Cooling, filtration and washing with water gave 2.7 g of pure 2,6-dichlorobenzonitrile. Stripping of the filtrate gave an additional 1 gram of pure 2,6-dichlorobenzontirile thus producing an overall yield of 84%.
