2-ethylanthraquinone catalytic cycle is a common method for preparing hydrogen peroxide on an industrial scale.
But such a large oxidized fused ring compound seems to be somewhat difficult to synthesize.(Until now, its production method has only Friedel-Crafts reaction of phthalic anhydride with ethylbenzene.)
Also you need to pay attention to the reaction yield.In the game,the reactor is still rough and many reaction conditions and post-treatments are difficult to carry out.(Such as Chromatographic separation method or other reaction environment)
Also,You can make Disulfuric acid by electrolysis of sulfuric acid.Then let the water to react with it.This process can get H2O2.
The reaction of peroxide with water at low temperature is a laboratory preparation method.The peroxide of the active metal does not seem to be easily prepared or stored, it seems to be somewhat expensive.
By the way,I have a small organic chemistry problem,I want to ask you about it.@Mr.CHEN
