Anthraquinone CAS 84-65-1 In Stock

Anthraquinone CAS 84-65-1 Overview

Anthraquinone (9,10-anthracenedione, C₁₄H₈O₂) is a light yellow crystalline powder with excellent thermal stability, low water solubility and good sublimation property. It serves as a critical organic intermediate widely used for manufacturing vat dyes, disperse dyes, acid dyes and pigments. It is also applied as a pulping additive in alkaline paper-making to accelerate delignification and boost pulp yield, as well as a raw material for hydrogen peroxide production. We supply ≥98% purity grade, available from stock, packed in 25kg bags.

Application

Anthraquinone 84-65-1 is mainly used in dye production and is the main raw material for mordant dyes, acid dyes, and vat dyes. Anthraquinone has been used as a raw material for anthraquinone dyes for a long time and holds an important position in the dye industry.

1. Dye Industry (Main Applications)

Anthraquinone-based dyes are the core intermediate molecules of the main ring. Through processes such as sulfonation, nitration, and chlorination, they are synthesized into reducing dyes, disperse dyes, acid dyes, and reactive dyes. These dyes have rich color tones, good sun resistance, and excellent wash fastness, and are widely used in textile printing and dyeing of polyester, cotton, and wool, as well as in the synthesis of organic pigments.

2. Papermaking and Pulp Production (Alkali-Fed Cooking Additives)

Added during the sulfate method / caustic soda method pulp production, they catalyze the removal of lignin and protect cellulose; they increase the yield of pulp, reduce the consumption of caustic soda, shorten the cooking time, and lower the load of black liquor treatment. They are applicable to wood pulp, bamboo pulp, and straw pulp, and belong to common pulp production additives.

3. Raw Materials for Hydrogen Peroxide Industry (Anthraquinone Process)

As a basic raw material, AQ is used to synthesize alkyl anthraquinones (such as ethyl anthraquinone), which is the working carrier precursor of the mainstream anthraquinone-based hydrogen peroxide process, and is used for large-scale production of hydrogen peroxide.

4. Fine Chemical Synthesis Intermediate

Synthesize various anthraquinone derivatives, fluorescent whitening agents, photosensitive materials, photoelectric functional materials, pesticide intermediates, anthraquinone disulfonic acid sodium (ADA, fertilizer / coal gas desulfurization).

5. Other Minor Applications

– Bird Repellent Raw Materials (Biological Bird Repellent Formulations)
– Some research directions: raw materials for the synthesis of pharmaceutical intermediates

Product features

1. Strong chemical stability, good heat resistance, and not easily decomposed.

2. Conjugated aromatic structure， serving as the core ring framework for dye synthesis.

3. Exhibits catalytic effect in the pulping system and is resistant to high-temperature cooking environment.

4. Low volatility， excellent storage stability， and not easily affected by moisture.

5. Can itself act as an oxidation-reduction medium and is suitable for the hydrogen peroxide production process.

Product Selling Points & Core Advantages

✅ Core intermediate for the dye industry: Anthraquinone (AQ) is applied in the synthesis of vat dyes, disperse dyes, acid dyes and reactive dyes. It delivers stable shade and outstanding color performance, serving as an irreplaceable raw material for AQ-series dyes.
