Dissolve 7.2 g (0.05 mol) of 2-naphthol in 40 ml of 5 per cent sodium hydroxide solution in the cold add a little more water if necessary. If the solution is highly coloured, add 1.5 g of decolourising carbon and filter the cold solution through a hardened filter paper. Pour the solution into a 100-ml conical flask and run in 7.0 g (5.8 ml, 0.05 mol) of benzoyl chloride. Stopper the flask and shake vigorously until the odour of benzoyl chloride has disappeared (10-15 minutes). Filter off the solid product on a Buchner funnel and wash it with a little cold water. Recrystallise it from about 60 ml of rectified spirit. Filter off the crystals which separate and dry them upon filter paper in the air. The yield of pure 2-naphthyl benzoate, m.p. 110 °C, is 11 g (89%).
