Embodiment 1

[0040]Add 60ml of water into a 250ml four-neck flask, start stirring, then add 1.6g of sodium hydroxide, stir evenly and heat up to 60°C, start adding 1,4-diaminoanthraquinone-2,3-dicarboxyimine 6.18 g, after adding the materials, heat up to 100°C, heat and stir for 1h, add 1g of decolorized activated carbon, stir for 30min, filter and rinse the activated carbon with 30ml of hot water, pour the filtrate into a 250ml four-necked flask, start stirring and heat up to 60 ℃, slowly add 2.08g of dilute sulfuric acid mixed with 98% sulfuric acid and 8ml of water dropwise, when the dilute sulfuric acid is added, raise the temperature to 100℃, keep the temperature for 1h, and use 10ml of 18.25% hydrochloric acid for acid analysis, after the seepage circle of the material on the filter paper is clear , filter while hot and rinse the filter cake with 100ml hot acid water, dry it for later use;

Embodiment 2

[0044] Use the 3% liquid water-soluble disperse dye that embodiment 1 prepares as the inkjet printer ink, after printing, handwriting is even, after separating out dyestuff on printing paper, dyestuff can not be dissolved again. Drops of water are added to the printed paper without ink spreading.

Embodiment 3

[0046] Use the 3% liquid water-soluble disperse dye that embodiment 1 prepares, add the ammoniacal liquor of 0.5% of ink gross mass, the ethylene glycol dimethyl ether of ink gross mass 1%, the JFC dispersant of ink gross mass 0.1%, stir and mix After uniformity, as an inkjet printer ink, after printing, the handwriting is uniform, and the dye will not be dissolved again after the dye is precipitated on the printing paper. Drops of water are added to the printed paper without ink spreading.

Abstract

The invention relates to a blue temporary water-soluble disperse dye, a preparation method thereof and an application thereof. The structural formula of the dye is shown in the specification. The preparation method comprises the following steps: obtaining 1, 4-diaminoanthraquinone-2, 3-dicarboxylic anhydride through carrying out a hydrolysis reaction and a ring closure reaction on 1, 4- diaminoanthraquinone-2, 3-dicarboxyl imine; adding p-carboxymethylsulfonyl aniline, and carrying out a reaction and acid precipitation to obtain a filter cake; and standardizing. So the dye is obtained. The dye is used to prepare ink jet printer ink, and is not subjected to secondary dissolution and does not diffuse with water after precipitated on printing paper, so the application range of ink jet printers can be broadened. According to the invention, the disperse dye has a high yield, the reactions may be completely carried out according to a theory amount, samples with the dye are brilliant in color, a molar extinction coefficient of the dye is substantially higher than molar extinction coefficients of like temporary water-soluble disperse dyes, and a problem of deficient blue varieties can be solved.

Description

technical field [0001] The invention relates to a dye technology, in particular to a blue water-soluble disperse dye and its preparation method and application. Background technique [0002] Most of the fuels currently on the market are oil-soluble dyes. Water-soluble disperse dyes are mainly used for dyeing and printing polyester fibers. In application, it can save the ordinary disperse dye sanding post-treatment process and dispersant, save energy, improve labor productivity, and can be mixed with reactive dyes for polyester / cotton one-bath dyeing, and the application is very convenient. After 20 years of research, this type of dye has a relatively rich color spectrum. However, the existing varieties on the market do not meet the actual needs, especially the requirements for more varieties of designs and higher dyeing efficiency. [0003] The Chinese patent application number 95110173 introduces a water-temporarily soluble blue disperse dye, which condenses 2-chloromethy...
