Abstract

The invention provides 5-chloronitroaniline-containing azoic disperse dyes and a preparation method thereof. The structural general formula of the disperse dyes is shown in a formula (I), wherein X is hydrogen or bromine; R is hydrogen, methyl or -NHCO-C1-C4 alkyl; R1 is ethyl, cyanoethyl, phenmethyl, allyl or -CH2CH2OR4, wherein R4 is methyl, ethyl or carbonyl; R2 is independent of R1 but has the definition of the R1; and R3 is hydrogen, methoxyl or ethyoxyl. The 5-chloronitroaniline-containing azoic disperse dyes are characterized in that: a diazonium component contains 2,4-binitro-5-chloroaniline or bromide thereof. The dyes have the advantages of excellent wet fastness and sublimation fastness, are suitable for dyeing terylene and blend fabrics thereof, and have low cost and wide application prospect.

Description

Technical field:

[0001] The invention relates to azo disperse dyes containing 5-chloronitroaniline, and relates to the preparation method and application of these dyes. Background technique:

[0002] At present, the disperse dyes with 2,4-dinitro-6-bromo(chloro)aniline as the diazo component are mostly used as dark varieties, and are widely used in polyester printing and dyeing, such as C.I. Disperse Blue 79:1, C.I. Disperse blue 291 and C.I. disperse violet 93, etc., but the wet fastness of these dyes is poor. After the polyester fabric is heat-set at high temperature, part of the dye will re-migrate to the surface of the fiber and contaminate the adjacent fabric. For this reason, disperse dyes of some new structures have appeared to solve the above problems. The diazo components of these new structure disperse dyes may be phthalimide bromides or single cyanide and double cyanide substitutions of bromides. Objects, or single cyanide, dicyanide structure of aniline. The co...
