Abstract
Improved composition of final forms of cationic dyes and their mixtures in liquid form when mixed to expand the colors of such classes as azine, oxazine, acridine, triazole, triazine, benthiazole and polymethine with reduced foaming and increased resistance to storage of roses. The improved composition allows to expand the color range of mixed dyes for dyeing and printing of fabrics from polyacrylonitrile fiber with high quality indicators. Options for utilization of coke oven gas and resin components isolated from coal coking waste by synthesis of intermediates based on it for the synthesis of triarylmethane dyes are considered. The main directions of improvement of technology of their production for various areas of application are defined. The reactions of aniline, phenol, toluene and their derivatives, naphthalene from coke chemical resin with subsequent production of target dyes from yellow to blue and violet colors are shown. Physicochemical and technological features of the formed tungsten-molybdenum varnishes on the basis of cationic basic dyes are resulted.
