preparation example Construction

[0026] The preparation method of above-mentioned active turquoise dye semi-finished product, comprises the following steps:

[0027] (a) Control the temperature of the reaction vessel to ≤65°C, add chlorosulfonic acid and copper cyanine to it, then raise the temperature to 120~135°C for 2~5 hours, then cool down to 60~70°C, add thionyl chloride to it for reaction 1 to 3 hours, then heat up to 85 to 100°C and react for 1 to 3 hours, bubble dry air into it for 1 to 3 hours, cool down to 20-30°C to obtain the first mixed solution, the chlorosulfonic acid, the The molar ratio of copper phthalocyanine and the thionyl chloride is 20~25:1~2:6~8; on the one hand, multiple cooling and heating are carried out during the reaction process, which is beneficial to suppress the progress of side reactions and improve the required product On the other hand, the solution after the reaction is bubbled to remove excess thionyl chloride. The conditions are simple and easy to operate, which is cond...

Embodiment 1

[0037] The present embodiment provides a kind of active turquoise dye semi-finished product, and its structural formula is as follows:

[0038] , where x=1, z=1, y=2.

[0039] Its preparation method comprises the following steps:

[0040] (a) Control the temperature of the reaction vessel at 65°C, add 1950kg of chlorosulfonic acid and 399kg of copper phthalocyanine into it, stir for 0.5 hours (the water vacuum ≤0.01Mpa during the feeding process and prevent material leakage) and raise the temperature to 120~135°C for 2~ 5 hours, then lower the temperature to 60~70°C and add 600kg of thionyl chloride (water vacuum ≤0.01Mpa during the feeding process to prevent material leakage) to react for 1~3 hours, then raise the temperature to 85~100°C for 1~3 hours , bubbling dry air into it for 1 to 3 hours, cooling down to 20-30°C to obtain the first mixed solution;

[0041] (b) Add ice water to another reaction vessel, and add 238kg of cyanuric chloride and quantitative aniline-2,5-...

Embodiment 2

[0046] The present embodiment provides a kind of active turquoise dye semi-finished product, and its preparation method is basically the same in embodiment 1, and difference is that the feeding ratio is not the same, thus the semi-finished product structural formula of preparation is:

[0047] , where x=1, z=1.5, y=1.5.

Abstract

The invention relates to a reactive turquoise blue dye semifinished product, and a preparation method and application thereof. The chemical structure general formula is disclosed as Formula (I), wherein 0<x<=2, 0<y<=2, 0<z<=2, and x+y+z=3.5-4; and preferably, 1<=x<=2, 1<y<=2, and 1<z<=2. The molecular formula of the semifinished product contains multiple sulfo-groups and sulfamido groups, and thus, the semifinished product is weakly alkaline on the whole. The phthalocyanine group can be introduced to enhance the color development property. When the reactive turquoise blue dye semifinished product is compounded with another semifinished product B into the dye, the fixation rate and deep dyeing property can be enhanced.

Description

technical field [0001] The invention belongs to the field of organic dyes and relates to a semi-finished dye, in particular to a semi-finished reactive turquoise dye, a preparation method and an application thereof. Background technique [0002] Reactive dyes, also known as reactive dyes, are a class of dyes that chemically react with fibers during dyeing. Such dye molecules contain groups that can chemically react with fibers. When dyeing, the dyes react with the fibers and form covalent bonds between them to form a whole, which improves the fastness to washing and rubbing. Reactive turquoise dye is a monomeric compound. The dyeing fastness of this dye is relatively low, especially the shade brightness is poor, and the dust is large when used, so it is not easy to wash. Therefore, a reactive turquoise blue dye semi-finished product is synthesized for the preparation of reactive turquoise blue dye to reduce dust and foam during use, thereby improving the washing effect. ...
