anthraquinone Application scenarios
1. Dye Industry
Production of various dyes and their intermediates
Anthraquinone is a key raw material for the synthesis of anthraquinone dyes. Through sulfonation, chlorination, nitration, and other reactions, a wide range of acidic, vat, disperse, and reactive dyes with complete color spectrum and excellent performance can be produced.
2. Paper Industry
Pulping and cooking additive
Adding a small amount of anthraquinone to the alkaline pulping liquor can accelerate delignification, shorten cooking time, increase pulp yield, and reduce wastewater load.
3. Chemical Production
Production of hydrogen peroxide (H₂O₂) The anthraquinone method (usually using derivatives of 2-ethyl or 2-tert-butyl anthraquinone) is the best method for the industrial production of high-concentration hydrogen peroxide.
4. Chemical Production
As a catalyst or additive
It can be used as a catalyst for the isomerization of vegetable oils, an accelerator in nickel plating, and a discharge printing assistant in dyeing and printing.
5. Agriculture
Bird repellent
Pesticide formulations (such as powders) can be used for seed treatment to prevent birds from pecking at seeds.
6. Pharmaceutical Field
Laxative active ingredient
Anthraquinone is the main active ingredient in herbal medicines (such as aloe vera) commonly used to relieve constipation.
Anthraquinone compounds in aloe vera have anti-inflammatory and antibacterial effects.
7. Scientific Research
Research reagents and standards
It can be used as a standard for quantitative analysis, quality control, and related biochemical experimental research.

Anthraquinone Usage
1. Uses Used as dye intermediates, paper cooking agent and hydrogen peroxide raw materials
2. Use as a pulp and paper pulp cooking aids, can reduce the amount of alkali, shorten the cooking time.
3. Use Most ofanthraquinoneis used in dyes, but the amount ofvapalizingaid used as pulp is rapidly increasing.
(1) for the production of dyes anthraquinone as raw materials, the sulfonation, chlorination, nitrification, etc., can be a wide range of dye intermediates for the production of anthraquinone disperse dyes, acid dyes, vat dyes, the reaction Dyes, etc., to form a full-color dye grade. According to statistics, anthraquinone dyes have more than 400 varieties, in the field of synthetic dyes occupy a very important position.
(2) used as a papermaking pulp cooking agent in the alkaline cooking liquor only by adding a small amount of anthraquinone, you can speed up thedelignification, shorten the cooking time, improve pulp yield and reducewasteload. There are more and more paper mills currently using anthraquinone additives. The consumption of anthraquinone as a cooking additive has grown rapidly. Anthraquinone and other applications. Anthraquinone compounds can be used for the production of high concentrations of hydrogen peroxide; in the fertilizer industry to produce desulfurization agent anthraquinone disulfonate. Used in the printing and dyeing industry asa dispensing aids.
4. Use of organic synthesis of high-level dye intermediates, such as indanthrene reductive dyes, acid dyes, some active dyes important raw materials. Used as paper cooking agent and hydrogen peroxide raw materials, etc., can reduce the amount of alkali, shorten the cooking time. Used as a papermaking pulp cooking agent in the alkaline cooking liquor only add a small amount of anthraquinone, you can speed up thedelignificationspeed, shorten the cooking time, improve the pulp yield, reducewasteload. There are more and more paper mills currently using anthraquinone additives.
