Document Type and Number:
WIPO Patent Application WO/1991/002772
Kind Code:
A1
Abstract:
Dispersed nonoazodyes are obtained by means of bromination of substituted nitrochlorobenzene of general formula (I), where X = H, NO2, Cl, Br, CN, amination of the obtained compound, subsequent diazotisation of 2-X-4-nitro-6-bromo-aniline and azocombination of the obtained diazonium salt with an azocomponent of general formula (II), where R = alkyl, allyl, oxialkyl, acyloxialkyl, cyanoalkyl, alkoxycarbonylalkyl, aralkyl, phenoxiethyl, R1 = H or R1 is one of the R, R2 = H, alkyl, alkoxigroup, R3 = H, Cl, alkyl, acylaminogroup, with subsequent obtaining of the desired product of structural formula (III), where Y = Br or CN, X, R, R1, R2, R3 - have the values analogous to those mentioned above.
