Problems solved by technology

[0003] However, Disperse Orange 30 has disadvantages in environmental protection: the intermediate 2,6-dichloro-p-nitroaniline used in the synthesis of Disperse Orange 30 has by-products of chlorinated benzene, chlorinated toluene and chlorinated phenol in the production process. Chlorinated benzene, chlorinated toluene and chlorinated phenol also exist by-products in the process of dispersing orange 30 dye. Chlorinated benzene, chlorinated toluene and chlorinated phenol can be absorbed through the skin, which has a great impact on human health and the environment. hazards, EU REACH regulations and OEKO-TEX Standard 100 have restrictions on this substance
[0004] However, by purifying the intermediates, the content of chlorinated benzene, chlorinated toluene and chlorinated phenol reaches the specified range, which requires complex processes, a large amount of equipment and labor, which makes the commodity expensive

preparation example Construction

[0061] The present invention also provides a preparation method of orange disperse dye according to the present invention, which comprises: in the presence of auxiliary materials, each dye component is carried out particle treatment with pulverizer; In the presence of a pulverizer, particle treatment was carried out, followed by mixing.

[0062] In some specific embodiments of the present invention, the various dye compound components of the orange disperse dye composition are mixed according to a specific proportion, and are mixed with a pulverizer such as a sand mill or a grinder in the presence of auxiliary agents and water. Carry out granulation treatment; the individual components in the orange disperse dye composition can also be granulated with a pulverizer such as a sand mill or a grinder in the presence of additives and water, and mixed in a specific proportion after granulation treatment.

[0063] In some specific embodiments of the present invention, the orange disp...

Embodiment 1

[0073] After dispersing and crushing 27 grams of compound of formula (I), 10 grams of compound of formula (II), 3.75 grams of compound of formula (III) and 1.5 grams of compound of formula (IV), add 22 grams of lignin 85A, 35.75 grams of dispersant MF Stir with 100 grams of water to disperse and dissolve, after continuous grinding or sand grinding to the end, repeat filtration, send to a spray drying tower through a pipeline for drying, and at the same time spray dust-proof oil evenly to obtain an orange disperse dye.

Embodiment 2～6

[0075] According to the structure and weight shown in Table 1, components A to D and auxiliary agents were mixed with water, and the method described in Example 1 was adopted to prepare orange disperse dye.

Abstract

The invention provides an orange disperse dye composition, an orange disperse dye and a preparation method and application of the orange disperse dye. The orange disperse dye composition comprises: acomponent A as shown in a formula (I), a component B as shown in a formula (II) and a component C as shown in a formula (III). The contents of chlorobenzene, toluene chloride and chlorinated phenols in the orange disperse dye composition disclosed by the invention all meet the requirements of Oeko-Tex Standard 100 and the requirements of European Union Reach regulations, and the orange disperse dye composition is an ecological and environment-friendly disperse dye composition. The orange disperse dye composition can reduce the production cost, reduce the dyeing sewage and effectively make up for the deficiency of disperse orange 30 in the market.

Description

technical field [0001] The invention relates to the field of dyes, in particular to an orange disperse dye composition, an orange disperse dye and a preparation method and application thereof. Background technique [0002] Disperse Orange 30 is recognized as an important orange disperse dye in the world, because it can not only obtain a medium-dark color with good compatibility in the dyeing of hydrophobic fibers (especially polyester fibers), but also has good sublimation and Light fastness. The azo-type disperse orange 30 disclosed on pages 804 to 805 of the first volume of "Encyclopedia of Dyestuffs" has excellent sublimation fastness and light fastness during dyeing, and is suitable for color matching of three primary colors. In the high temperature and high pressure dyeing method, it can be combined into medium and dark colors, so it has become a widely used main color dye. [0003] However, Disperse Orange 30 has disadvantages in environmental protection: the interme...
