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.

蒽醌的用法

1.用途 用作染料中间体、纸张蒸煮剂和双氧水原料

2.用作纸浆和纸张的蒸煮助剂,可以减少碱的用量,缩短蒸煮时间。
3.用途 蒽醌大部分用于染料,但用作纸浆的汽化萘的用量也在迅速增加。

(1)以生产染料的蒽醌为原料,经磺化、氯化、硝化等反应,可得到多种染料中间体,用于生产蒽醌分散染料、酸性染料、大桶染料、反应染料等,形成全色系染料。据统计,蒽醌染料有 400 多个品种,在合成染料领域占有十分重要的地位。

(2)用作造纸纸浆蒸煮剂 在碱性蒸煮液中只需加入少量蒽醌,就可以加快木质素化,缩短蒸煮时间,提高纸浆得率,减少废料。目前使用蒽醌添加剂的造纸厂越来越多。作为蒸煮添加剂,蒽醌的消费量增长迅速。蒽醌及其他应用。蒽醌化合物可用于生产高浓度过氧化氢;在化肥工业中用于生产脱硫剂蒽醌二磺酸盐。在印染工业中用作点染助剂。
4.利用有机合成高级染料中间体,如茚还原染料、酸性染料、某些活性染料的重要原料。用作造纸蒸煮剂和双氧水原料等,可减少碱用量,缩短蒸煮时间。用作造纸纸浆蒸煮剂只需在碱性蒸煮液中加入少量蒽醌,就可以加快脱木速度,缩短蒸煮时间,提高纸浆得率,减少废渣量。目前使用蒽醌添加剂的造纸厂越来越多。
