Embodiment 1

[0036] Synthetic target compound: Huang 22#

[0037]

[0038] The synthesis principle is

[0039] Diazo reaction:

[0040]

[0041] coupling reaction

[0042]

[0043] Add 90g of water, 23.75g of cyanoethylbenzylaniline with a purity of 99.5%, 35ml of alcohol, and 80ml of hydrochloric acid with a concentration of 36.5% in the coupling component dissolving pot to obtain a coupling component solution after dissolution.

[0044] Add 30g of 98% sulfuric acid and 29.54g of salt-free nitrosylsulfuric acid with a content of 42% to the diazonium reaction kettle in sequence, and add 2,6-dibromo-4-carboxymethanesulfonylaniline within 1 hour at a temperature of 1°C. 38.16g. After the addition, the diazotization reaction was carried out at 40°C under normal pressure. After 7 hours of reaction, a diazonium salt solution was obtained, which was then added to the coupling reaction kettle.

[0045] Add the measured coupling component solution and ammonia water into the diazonium s...

Embodiment 2

[0049] 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

[0051] 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 discloses a temporarily water-soluble disperse dye and a preparation method and application thereof. The dye has a structural formula shown in the specifications, wherein R1 is -C2H4CN or-C2H5. The dye has high dyeing exhaustion property and is suitable for dyeing superfine polyester fibers; the chromatographic peak is wide; the color of filtrate is light, the yield is high, and wastewater is convenient to treat; and the problem that black cannot be matched is solved, and light fastness and washing fastness are high. The dye can be directly standardized to be used for preparing ink of an ink-jet printer, cannot be redissolved after being precipitated on printing paper, and cannot be diffused when meeting water, so that the application range of the ink-jet printer is expanded.

Description

[0001] technical field [0002] The invention relates to a dye technology, in particular to a water-temporarily soluble disperse dye and its preparation method and application. Background technique [0003] Most of the dyes currently on the market are oil-soluble dyes. Temporary water-soluble disperse dyes are mainly used for dyeing and printing of polyester fibers. When applied, it can save ordinary disperse dyes after sanding and dispersants, save energy, improve labor productivity, and can be mixed with reactive dyes for polyester fibers. Or cotton one-bath dyeing, the application is very convenient. Temporary water-soluble disperse dyes have been researched for 20 years, and their chromatograms have been relatively rich. However, the existing varieties on the market do not meet the actual needs, especially the requirements for more varieties and higher dyeing efficiency. . [0004] The Chinese patent application number 95110173 introduces a water-temporarily soluble b...
