Diazotization method of wet nitroaniline

The invention provides a diazotization method of wet nitroaniline, and relates to the field of dye synthesis. The diazotization method comprises following steps: step one, evenly stirring sulfuric acid (98%) and nitrosyl sulfuric acid (40%) in a diazotization reactor; and step two, adding wet nitroaniline into the diazotization reactor at a controlled temperature of -10 to 40 DEG C to obtain diazotization salts, wherein the mole ratio of sulfuric acid to nitrosyl sulfuric acid to diazotization component is 1.0-6: 1.02-1.1: 1. The quality of the provided wet dye is the same as that of a dry product, the diazotization component does not need to be dried, and the provided dye is energy saving and environmentally friendly.

Azo disperse dye mixtures

The present invention refers to a dye mixture comprising an azo dye of the formula (I) wherein each of X and X1independently is chlorine or bromine; R1is absent or is C1-4alkyl; and each of R2and R3independently is hydrogen, C1-6alkyl or cyanoethyl; but when R1is absent, R2is n-butyl or cyanoethyl and R3is cyanoethyl; and further dye components according to claim 1, a method for the preparation of such mixtures and a method for coloring a synthetic textile material or fiber blend thereof using such mixtures.

Synthesis and Spectral Characterization of Blue Dyes of the Benzene Series

53 Donor-acceptor substituted azo dyes of the benzene series were prepared by diazonium-coupling reactions (1a-s) or halogen-cyanide exchange (->2a-x, 3a-j).Described are the preparation of the amines 4a-m and the coupling compounds 5a-t and the procedure of diazotizing and coupling.The colouristic and spectroscopic data show that compounds of the general formula 1 are excellent brilliant blue azo dyes usefull for dyeing polyester material.
