Abstract
Azo compounds of the formula AQ--NH--R--N = N--R<1> and their sulphonic acids wherein AQ = anthraquinonyl and R and R<1> stand for arylene and aryl respectively of the benzene or naphthalene series are made by interacting an anthraquinone compound which has a replaceable negative substituent with a compound of the formula NH2.R.N = N--R<1>. The sulphonic acids are made either by (1) sulphonating the azo compounds, or (2) by starting from sulphonated components. The sulphonation may be effected either by treating the azo compounds with sulphonating acids or a halogen azo compound with a sulphite. The sulphonated compounds are wool dyes. All the compounds may be substituted by halogen, methyl, amino, acylamino, hydroxy or alkoxy groups. In the examples: (1) sodium 4-bromo- or chloro-1-aminoanthraquinone-2-sulphonate is condensed with p-aminoazobenzene in presence of sodium carbonate and bicarbonate, cuprous chloride, alcohol and water (green on wool), (2) 4-bromo-1-aminoanthraquinone-2-sulphonic acid is condensed as in (1) using copper borate instead of copper chloride, (3) similar to (1) using copper oxalate, sulphate or nitrate, (4) sodium 4-bromo-1 - aminoanthraquinone - 2 - sulphonate is condensed with sodium 4-aminoazobenzene-4<1>-sulphonate as in (1) (green on wool), (5) 2 : 4-dibromo - 1 - aminoanthraquinone - 5 - sulphonicacid and p-aminoazobenzene are condensed as in (1), (6) 5 - chlor - 4 - bromo - 1 - aminoanthraquinone - 2 - sulphonic acid and p - aminoazobenzene are condensed as in (1) using copper nitrate (yellowish green on wool), (7) the product of (1) is sulphonated (yellowish green on wool), (8) similar to (4) using 4-benzeneazo-a -naphthylamine-6(7)-sulphonic acid (green on wool), (9) 1-chloranthraquinone, p-aminoazobenzene, sodium carbonate and cuprous iodide are heated in o - dichlorobenzene, (10) sodium anthraquinone - 1 - sulphonate and p - aminoazobenzene are heated with methyl alcohol under pressure, (11) 4-chloro-1-benzoylaminoanthraquinone, p-aminoazobenzene, sodium carbonate and cuprous iodide are heated in o-dichlorobenzene. Specification 455,711 is referred to.
