The industrial, large-scale preparation of hydrogen peroxide relies fundamentally on the cyclic auto — Hydrogen Chemistry Question

💡 Solution & Explanation

In the industrial process, 2-ethylanthraquinol is subjected to air oxidation (auto-oxidation), which yields hydrogen peroxide ($H_2O_2$) alongside 2-ethylanthraquinone. The quinone is then catalytically reduced back to 2-ethylanthraquinol using $H_2$/Ni to repeat the cycle.
