Abstract

Disulphonamides of the general formula <FORM:0577387/IV/1> wherein positions ortho or para to the hydroxyl groups are reactive and A represents a divalent radicle of at least 8 carbon atoms and includes at least one benzene ring, are made by condensing an appropriate naphthalene sulphonyl chloride containing an acyloxy or oxycarbalkoxy (i.e. -O-COO Alkyl) group in the 1-position with an appropriate aromatic diamine and hydrolysing the acyloxy or oxycarbalkoxy group. The positions ortho or para to the hydroxyl groups may be unsubstituted or they may contain an atom or group, e.g. a chlorine or bromine atom or a sulphonic or carboxylic acid group, which does not inhibit dye-coupling reactions, and which is generally split off during such reactions. Condensation may be effected in aqueous or non-aqueous media, e.g. in ether, acetone, acetic acid or dioxane, and a basic agent such as pyridine, a trialkylamine, triethanolamine or sodium carbonate, hydroxide or acetate, may be present. In an example, 1 - oxycarbethoxynaphthalene - 2 - sulphonyl chloride is condensed with 4 : 41-diaminodiphenyl ether, 1 : 4-bis-(aminomethyl)-benzene, 1 : 5 - naphthylenediamine, 4 : 41 - diaminodi - phenylmethane, 4 : 41-diaminodiphenylmethane-3 : 31-dicarboxylic acid or p-bis-(b -aminoethyl)-benzene, and the product hydrolysed with an aqueous-alcoholic solution of potassium hydroxide. Additional diamines specified are 2 : 21-, 2 : 41-and 4 : 41-diaminostilbenes and benzidine. The nuclei of such diamines may be substituted by groups which do not enter into dye-coupling reactions, e.g. by hydrocarbon radicles (e.g. alkyl, aryl or aralkyl), halogen atoms or ether, nitro, hydroxy, amino, hydrocarbon-substituted amino, carboxy, nitrile, sulphonic, sulphone, sulphinic or sulphide groups. Specifications 497,698, 544,189, 545,433, [Group XX], 554,302 and 556,858, [Group XX], are referred to. Naphthalene sulphonyl chlorides used as starting materials above are prepared by treating 1-hydroxynaphthalene sulphonic acids, such as the 1 : 2- and 1 : 5-isomers, with a chloroformic ester or with an acylating agent, such as acetic anhydride or acetyl p chloride, and treating the products with phosphorus pentachloride.
