2-Ethylanthraquinone Market Summary

2-Ethylanthraquinone often abbreviated as 2-EAQ (CAS No. 84-51-5), is a critical organic synthesis intermediate belonging to the anthraquinone class. Its market position is fundamentally defined by its almost exclusive use as the working substance in the modern industrial production of Hydrogen Peroxide (H2O2). The molecular structure of 2-EAQ allows it to be efficiently hydrogenated and subsequently oxidized in a cyclic process, making it indispensable for the high-volume production of H2O2 globally.
The 2-Ethylanthraquinone industry is characterized by the following key features:
* Dominance by Hydrogen Peroxide Production: The primary driver for 2-EAQ is the Anthraquinone Process (or Riedl-Pfleiderer Process) for producing H2O2. This captive demand, tied to the essential use of H2O2 across industrial sectors (pulp, paper, chemicals), ensures market stability.
* Complex Multi-Step Synthesis: The mainstream production method is the Phthalic Anhydride Method (Phthalic Anhydride Process). This involves a two-step reaction: first, the synthesis of 2-(4-Ethylbenzoyl)benzoic acid (BE Acid) using ethylbenzene and phthalic anhydride in the presence of Aluminum Chloride (AlCl3), followed by ring closure using fuming sulfuric acid. The relative availability of the raw materials makes this the dominant industrial route. Other routes, such as the 2-Formylanthracene conversion or the direct oxidation of 2-Ethylanthracene, are deemed less viable due to raw material sourcing difficulties or impractical synthesis steps.
* Chinese Manufacturing Hegemony: China is the largest global producer, consumer, and exporter of 2-EAQ. This concentration results from China's robust fine chemical industry and its large domestic production capacity for H2O2.
The global market for 2-Ethylanthraquinone is estimated to be valued in the range of 160-320 million USD in 2025. Driven by stable, foundational demand from the chemical and pulp & paper industries for H2O2, the market is projected to achieve a moderate Compound Annual Growth Rate (CAGR) in the range of 1.8%-3.2% through 2030.
