Abstract

PURPOSE: To prepare the titled compound useful as an intermediate of polymeric materials, photographic chemicals, dyes, etc., in high yield and quality, by reacting naphthalenesulfonic acid and/or naphthalenesulfonic acid salt with thionyl chloride in an inert organic solvent.
CONSTITUTION: A naphthalenesulfonylchloride compound of formula II (n is 2W4; R is H, nitro, halogen, alkoxy, etc.; m is 4W6, provided that m+n=8) is prepared by reacting a naphthalenesulfonic acid and/or a naphthalenesulfonic acid salt of formula I (M is H, alkali metal, alkaline earth metal, etc.) with thionyl chloride in an inert organic solvent such as chloroform, in the presence or absence of a chlorination assistant (e.g. acid amide). The amount of thionyl chloride is 1W5mol per 1mol of the sulfo-group of the compound of formula I. The reaction temperature is 0W200°C. The excess thionyl chloride, etc. can be recovered and reused easily by distillation.
