Problems solved by technology

However, because C.I. Disperse Yellow 23# is a dye obtained by diazotization of p-aminoazobenzene and coupling with phenol, among which p-aminoazobenzene will produce substances that are carcinogenic to the human body, it has been completely banned
In addition, the proportion of anthraquinone dyes in the disperse dyes made by C.I. Disperse Yellow 23# is relatively large, the cost is high, and the cost performance is low

preparation example Construction

[0039] The preparation methods or sources of the specific compounds used in the examples are as follows.

[0040] Compound of formula (I-1): prepared by diazotizing 2,6-dichloro-4-nitroaniline and coupling with N-ethyl-N-chloroethyl-m-toluidine by a known method.

[0041] The compound of formula (I-2) is prepared by diazotizing 2,4-dinitro-6-bromoaniline by a known method and coupling with N-ethyl-N-chloroethyl-m-toluidine.

[0042] The compound of formula (I-3): prepared by diazotizing 2-chloro-4-nitroaniline with N-ethyl-N-chloroethylaniline by a known method.

[0043] The compound of formula (I-4) is prepared by diazotizing 2-chloro-4-nitroaniline and coupling with N-ethyl-N-chloroethyl-m-toluidine by a known method.

[0044] Compound of formula (II): commercial product C.I. Disperse Blue 360;

[0045] Compound of formula (III-1): C.I. Disperse Yellow 64 commercially available from Zhejiang Runtu Co., Ltd.;

[0046] Compound of formula (III-2): C.I. Disperse Yellow 54 commercially avai...

Embodiment 1

[0052] Combine 28 grams of component A of formula (I-1), 22 grams of component B of formula (II), 20 grams of component C of formula (III-2), and 12 grams of component D of formula (IV-3) , 18 grams of component E of formula (V) and 262 grams of dispersing agent CNF, add 543 grams of water, grind and disperse with a sand mill, and spray dry to prepare disperse dyes.

Embodiment 2-15

[0064] The distribution ratio of each group in Examples 2-15 is shown in Table 2. The preparation method of disperse dyes is the same as that in Example 1. The moisture in Table 2 refers to the moisture of commercial products.

[0065] Table 2 (Unit: grams)

[0066]

[0067]

[0068] With reference to the method of Example 1, weigh 1 gram of the finished dye products of Examples 2-15 into a 500 ml volumetric flask to prepare a disperse dye suspension. OWF: 4% absorb 40ml of disperse dye suspension and 60ml of water, adjust the dye bath pH to 5 with acetic acid, then heat to 60℃, and put 2g of polyester fiber into high temperature and high pressure dyeing, and heat to 130 in 35min ℃, keep for 45min, cool to 80℃ for sampling.

Abstract

The invention relates to a disperse dye composition, a disperse dye, and a preparation method and application for the disperse dye. The disperse dye composition comprises: at least one component A asshown in a formula (I) which is described in the specification; a component B as shown in a formula (II) which is described in the specification; at least one component C as shown in a formula (III) which is described in the specification; at least one component D as shown in a formula (IV) which is described in the specification; and a component E as shown in a formula (V) which is described in the specification. The disperse dye provided by the invention comprises the disperse dye composition and auxiliary materials, has high strength and low cost, and has characteristics like good lifting power, good blackness and excellent rubbing fastness and washing fastness when being applied to dyeing of a hydrophobic fiber material.

Description

Technical field [0001] The invention relates to a disperse dye composition, a disperse dye and a preparation method and application thereof. The disperse dye is suitable for dyeing polyester and its blended fabric. Background technique [0002] With the gradual increase of the government's efforts in pollution control, the Chinese people's awareness of environmental protection has increased year by year, which has had a greater impact on the development of dye companies. The traditional disperse dyes made by C.I. Disperse Yellow 23# have good level dyeing properties and excellent fastnesses. They are highly recognized by users and have a relatively large market share. However, because C.I. Disperse Yellow 23# is a dye obtained by diazotizing p-aminoazobenzene and coupling with phenol, among which p-aminoazobenzene can produce substances that are cancerous to the human system, it has been completely banned. In addition, the disperse dyes prepared by C.I. Disperse Yellow 23# have...
