A solution of 3 g of para-n-hexyl benzoic acid is refluxed in 7 ml of thionyl chloride for 2 hours. The thionyl chloride is eliminated by distillation under atmospheric pressure, followed by the distillation of the acid chloride under reduced pressure and under a dry nitrogen stream. This gives a product with a boiling point of 153° C. under 1.2 mm Hg.
