2-Ethylanthraquinone is mainly used as a working carrier for the preparation of hydrogen peroxide by the anthraquinone method. It is also used in medicine, dye intermediates, photocurable resin catalysts, photodegradable films, coatings and photopolymerization initiators. Among them, the demand for hydrogen peroxide industry accounts for more than 90% of the domestic demand for 2-ethylanthraquinone.
At present, large-scale hydrogen peroxide manufacturers at home and abroad use the anthraquinone method to produce hydrogen peroxide. The output and quality of 2-ethylanthraquinone greatly affect the development of hydrogen peroxide manufacturing and related industries. With the rapid development of the hydrogen peroxide manufacturing industry in recent years, the supply of 2-ethylanthraquinone has grown rapidly.
In recent years, the domestic production capacity of 2-ethylanthraquinone has grown rapidly. It is roughly estimated that the total production capacity has reached about 30,000 tons per year, mainly concentrated in East China, and most of them are operated in an intermittent order production mode. In the past ten years, domestic consumption of 2-ethylanthraquinone has grown at an average annual rate of 8%, and the domestic consumption of 2-ethylanthraquinone in the past year is about 7000-8000 tons.
