Synthesis of picryl chloride

Preparation of picryl chloride

Preparation of picryl chloride

Preparation of picryl chloride

Pyridine (7.9) is added to a hot solution of picric acid (22.9 g) in 95 % alcohol (200 ml); on cooling, pyridine picrate (30.1 g, 98%), m.p. 166°, separates. Dry pyridine picrate (1 mole), phosphorus oxychloride (0.67 mole), and benzene (250 ml) are boiled under reflux for 15min; the benzene layer and the oil that separates are washed separately with hot water; after removal of the benzene, the benzene layer affords 73 % and the oil 25 % of picryl chloride, m.p. 79-81°C.
