| titleOfInvention | Monoazo dyestuff and quaternary ammonium salts thereof |
| abstract | The invention comprises monoazo dyes free from SO3H groups and of formula <FORM:1111236/C4-C5/1> wherein A is the radical of a diazo component, R is H or CH3, R1 is a substituent other than an SO3H or COOH group, R2 is an aliphatic radical, R3 and R4 are H, alkyl, alkoxymethyl, aryl or alkoxycarbonyl radicals and m is 0, 1 or 2; and the quaternary nitrogen derivatives thereof wherein the 2- or 3-nitrogen atom of the triazole ring is further substituted by an alkyl or benzyl group. The dyes are prepared by the usual azo coupling reaction using as coupling components N-(1,2,3-triazolyl-alkyl)-anilines or quaternary N derivatives thereof (see Division C2), followed when desired by an N-alkylation or benzylation. In Examples the preparation of dyes using diazo components of the benzene, benzothiazole, thiadiazole, thiazole and triazole series is described. The dyes yield yellow, red and red-blue shades on polyamide and polyester fibres (unquaternated dyes) and on polyacrylonitrile and polydicyanoethylene fibres (quaternated dyes).ALSO:Compounds of formula <FORM:1111236/C2/1> wherein R is H or CH3, R1 is a substituent other than COOH or SO3H, R2 is an aliphatic radical, R3 and R4 are H or alkyl, aryl, alkoxymethyl or carboalkoxy radicals and m is 0, 1 or 2 and derivatives thereof wherein the 2- or 3-N atom of the triazole ring is quaternated are described. They are used as intermediate, in the preparation of azo dyes (see Divisions C4-C5). In examples (1) N-ethyl-N-{b -[1,2,3-triazolyl-(1)]-ethyl}-aniline is prepared by condensing N-ethyl-N-b -chloroethyl-aniline or the sulphuric acid semi-ester of N-ethyl-N-b -hydroxyethyl-aniline with sodium azide to form N-ethyl-N-b -azido-ethyl-aniline and reacting this with acetylene; (2) the compound prepared in (1) is N-methylated with dimethyl sulphate; (3) N - ethyl - N - {b - [1,2,3 - triazolyl - (1)]-ethyl} - 3 - methylaniline is prepared as in (1) using N - ethyl - N - b - chloroethyl - m - toluidine; (4) N - ethyl - N - {b - [1,2,3 - triazolyl-(1)] - ethyl] - 3 - acetylaminoaniline is prepared from the compound described in (1) by nitration, reduction of nitro to amino and acetylation. Many other compounds of the above formula are listed. |
