Synthesis of 4-nitrobenzoyl chloride

Preparation of 4-nitrobenzoyl chloride

20 g of 4-nitrobenzoic acid and 25 g of phosphorus pentachloride are mixed in a 250-ml flask fitted with a reflux air condenser in a fume cupboard. The flask is heated on a water bath with occasional shaking until the evolution of hydrogen chloride nearly ceases and a clear homogeneous liquid is obtained. The reaction product is transferred to a distilling flask and distilled up to 220° C to remove phosphorus oxychloride. The residue of 4-nitrobenzoyl chloride may be purified by crystallisation from carbon tetrachloride or, by distillation under reduced pressure b.p. 155°C/20mm. Yield 90%, yellow needles; m.p. 73°C.
