Abstract
275,220. Geigy Akt.-Ges., J. R. July 29, 1926, [Convention date]. Monoazo dyes; lakes. - Monoazo dyes are obtained by diazotizing an aminosulphobenzoic acid having the sulpho group in the o-position to the amino group and coupling with a usual coupling component. The use as components of 1 : 8- naphthylenediamine-3 : 6-disulphonic acid or of compounds containing a cyanuric nucleus is excepted. In examples, (1) 2-chlor-5-amino-4- sulphobenzoic acid is diazotized and coupled with #-naphthol; the product is a fiery red powder giving a calcium or barium lake of more fiery tint and faster to light than Lake red C, and (2) diazotized 2-chlor-5-amino-4-sulphobenzoic acid is coupled in acid solution with 2 : 8 : 6-aminonaphthol sulphonic acid; the product dyes wool in a sulphuric acid bath vivid bluish-red tints fast to light, the fastness can be increased by after-chroming. By using pyrazolones as coupling components, dyestuffs giving greenish or yellow tints, very fast to light, are obtained. 2-Chlor-4-amino-5-sulphobenzoic acid is also specified as a diazo component. 2-Chlor-5-amino-4-sulphobenzoic acid is made by oxidizing o-chlor-p-toluenesulphonic acid, nitrating the carboxylic acid thus produced, and reducing the product. 2-Chlor-4-amino-5-sulphobenzoic acid is made by sulphonating o-chlor-p-nitrotoluene, oxidizing to produce the carboxylic acid, and then reducing the nitro group.
