Description
SPECIFICATION
Azo reactive dyestuffs
The present invention relates to azo reactive dyestuffs of the formula
wherein
D= the radical of a naphthalene-mono-, -di- or -tri-sulphonic acid,
R=hydrogen, methyl or ethyl and
X=hydrogen, C1-C4-alkyl, C1-C4-alkoxy, halogen, such as fluorine, chlorine or bromine, or a
carboxyl, sulpho or acylamino group, such as acetylamino, ureido, formylamino or oxalylamino.
Examples of a mines of the formula D-NH2 (Il) are the following: 2-amino-naphthalene-1 -sulphonic acid, 2-amino-naphthalene-1 5-disulphonic acid, 2-amino-naphthalene- 1 ,5,7-trisulphonic acid, 2-amino-naphthalene-3,6-disulphonic acid, 2-aminonaphthalene-3,6,8-trisulphonic acid, 2-amino-naphthalene-4,8-disu Iphonic acid, 2-amino-naphthalene4,6,8-trisulphonic acid, 2-a mino-naphthalene-5,7-disulphon ic acid, 2-a mino-naphthalene-6,8disulphonic acid, 2-amino-naphthaíene-6-sulphonic acid, 2-amino-naphthalene-8-sulphonic acid, 1amino-naphthalene-4-sulphonic acid, 1 -amino-naphthalene-5-sulphonic acid, 1 -amino-naphthalene-6- sulphonic acid, 1 -amino-naphthalene-7-sulphonic acid, 1 -amino-naphthalene-4,6-disulphonic acid, 1 a mino-naphtha lene-4.7-disulphonic acid, 1 -amino-naphtha lene-3,6-disulphonic acid, 2-am ino-6-nitro- naphthalene-4,8-disulphonic acid and 2-a mino-6-acetylamino-naphthalene-4,8-disu Iphonic acid.
Preferred compounds correspond to the formulae
wherein
R and X have the meaning indicated above and R,=hydrogen or suipho, and
wherein
R, R, and X have the meaning indicated above.
Compounds of the formulae (Ill) and (IV) in which
a) X=hydrogen,
b) X=sulpho,
c) X and R=hydrogen, or
d) X=sulpho and
R=hydrogen, are particularly preferred.
The invention furthermore relates to a processforthe preparation of the compounds of the formula (I). It consists of a procedure in which dyestuffs of the formula
wherein
D and R have the meaning indicated above, are subjected to condensation reactions with 2,4,6-trifluoro-1 ,3,5-triazine, hydrofluoric acid being split off, and the resulting difluoro compound is reacted with an amine of the formula
wherein
X has the meaning indicated above, hydrofluoric acid being split off, to give (I).
The condensation of the dyestuffs (V) with s-trifluorotriazine is preferably carried out in aqueous solution or suspension, at low temperature and at a weakly acid, neutral to weakly alkaline pH value.
The condensation reaction is advantageously carried out in the pH range of 3-5. The hydrogen fluoride liberated is buffered by adding aqueous alkali metal hydroxides, carbonates or bicarbonates.
The reaction of the difluoro compound with the amines (VI) is likewise preferably carried out in aqueous solution or suspension. at low temperature and at a weakly acid, neutral to weakly alkaline pH value.
The hydrogen fluoride liberated during the condensation reaction is neutralised by adding aqueous alkali metal hydroxides, carbonates or bicarbonates. In general, isolation of the difluoro compound is dispensed with.
In the case where X=sulpho or carboxyl, the dyestuffs (I) can also be prepared by a process in which p-sulphanilic acid or 4-carboxy-aniline is first reacted with s-trifluorotriazine and the condensation with the dyestuff (V) is then carried out.
A further possibility for the preparation of (I) consists of a process in which diazotised amines (II) are combined with coupling components of the formula
wherein
X and R have the meaning indicated above,
in a weakly acid, neutral to weakly alkaline range.
The dyestuffs (V) are obtained by coupling the diazotised amines (II) with I-acid under such
conditions that the coupling preferably takes place in the o-position reiative to the hydroxyl group of the
I-acid. However, coupling with a N-acylated I-acid is in general preferred, the acyl radical subsequently
being split off by warming in an acid or alkaline medium. Possible acyl radicals are, in particular, acetyl, ca rba moyl, methoxycarbonyl, ethoxycarbonyl or--COO-(l-acid urea by reaction with phosgene).
Examples of amines (VI) are the following: aniline, 4-methyl-aniline, 4-ethyl-aniline, 4-iso-propylaniline, 4-methoxy-aniline, 4-ethoxy-aniline, 4-iso-propoxy-aniline, 4-fluoroaniline, 4-chloroaniline, 4bromoaniline, 4-ca rboxy-aniline, 4-sulpho-aniline, 4-acetylamino-aniline or 4-carbamoyl-aniline.
The new dyestuffs are suitable for dyeing and printing materials containing hydroxyl groups or amide groups, such as textile fibres-, filaments and fabrics of wool, silk or synthetic polyamide, and polyurethane fibres, and for dyeing and printing natural or regenerated cellulose with dyeings and prints which are fast to washing, the treatment of cellulose materials appropriately being carried out, by the processes disclosed for reactive dyestuffs, in the presence of acid-binding agents and if appropriate by the action of heat.
The formulae indicated for the dyestuffs are those of the corresponding free acids. In general, the dyestuffs were isolated and employed for dyeing in the form of the alkali metal salts, in particular the Na salts.
EXAMPLE 1
55.3 g of the dyestuff of the formula 1 ,5-disulpho-naphthalenet 2 azo 2 21 -hydroxy-3-su Ipho-6amino-naphthaiene are dissolved in a mixture of 400 ml of water and 200 g of ice. 14 g of strifluorotriazine are then added dropwise and a pH value of 3.5-4.5 is simultaneously maintained by adding 20% strength sodium carbonate solution. When the acylation reaction has ended, 9.3 g of aniline are added, the pH value is adjusted to 6 with 20% strength sodium carbonate solution and the mixture is stirred at pH 6 until the second condensation reaction has ended. The temperature is 0--100.
The dyestuff is separated out by adding sodium chloride, filtered off dried and ground. A light red powder which dissolves in water giving an orange-coloured solution results. The dyestuff corresponds to the formula

55.3 g of the dyestuff of the formula 1 ,5-disulpho-naphthalene( 2 azo 2 1 -hydroxy-3-sulpho-6amino-naphthalene are stirred in a mixture of 300 ml of water and 100 g of ice. An ice-cold aqueous solution of 28.8 g of 2,4-difluoro-6-(4'-sulphophenylamino)-1 ,3,5-triazine is then added and the condensation reaction is carried out in the pH range of 5 to 6 and in the temperature range of O to 150. The dyestuff is salted out, filtered off, dried and ground. The dyestuff is identical to the product obtained according to Example 2).
