Title: METHOD FOR PRODUCING AZO DYE, ORGANIC AMINE SALT, METHOD FOR PRODUCING ORGANIC AMINE SALT, AZO COMPOUND AND METHOD FOR PRODUCING AZO COMPOUND
Abstract:
A method for producing an azo dye wherein: an organic amine salt that is a salt of an azo compound represented by formula (C) and an organic amine represented by formula (D) is obtained by reacting a diazonium salt represented by formula (A) with a compound represented by formula (B); an azo compound represented by formula (F) is obtained by reacting the organic amine salt sequentially with a sulfonyl compound represented by formula (E) and a chlorinating agent in this order; and an azo dye represented by formula (H) is obtained by reacting the azo compound represented by formula (F) with an amine represented by formula (G). An organic amine salt; a method for producing an organic amine salt; an azo compound; and a method for producing an azo compound. In the formulae, R1 represents an electron-withdrawing group; n represents a number of 0-4; each of R4-R6 represents an alkyl group; R2 represents an alkyl group or an aryl group; and R3 represents a hydrogen atom or an alkyl group.
