2-ethylanthraquinone

2-Ethylanthraquinone (CAS 84-51-5) is the primary working carrier used in the anthraquinone process for industrial hydrogen peroxide production. It functions as a hydrogen shuttle, cycling between oxidized and reduced forms to generate H2O2 at commercial scale. The dominant application is as the active working solution component in continuous hydrogen peroxide manufacturing plants. Process efficiency and purity of the carrier directly impact plant yield and output quality in these large-scale operations.

In UV-curable coatings and printing inks, it acts as a photoinitiator, triggering radical polymerization upon UV exposure. This allows for the rapid curing of films on paper, packaging, and various industrial substrates. Adhesive and sealant formulators incorporate it into UV-cure systems where fast, solvent-free curing is required. It is particularly effective on both flexible and rigid substrates used in modern manufacturing and assembly.

Textile and paper processors use hydrogen peroxide generated via these plants for bleaching operations. Consistent carrier quality is a critical supply chain consideration for these upstream industrial chemical processes. The product is supplied as a pale yellow to yellow crystalline powder or flake. Technical grade is the standard commercial form, with purity specifications typically at 98% or higher for process and formulation use.

Bulk quantities are available for H2O2 plant operators to maintain their working solutions. Smaller packaging options are also provided to serve photoinitiator and specialty chemical formulation buyers globally.
