purpose
generated by hydrogenation in solvent2-ethyl anthrahydroquinone, regenerated upon reoxidation2-ethyl anthraquinone and hydrogen peroxide, this reaction is used industrially to produce hydrogen peroxide. from phthalic anhydride and ethylbenzene through font-family–gram reaction, can also be produced by1,4-naphthoquinone and2-ethyl-1,3 –butadiene via diels–produced by alder diene synthesis and dehydrogenation reaction. it is used to prepare hydrogen peroxide and as a dye intermediate. it is also used as a sensitizer for photosensitive resins, photocurable resin catalysts, photodegradable films, coatings and photosensitive polymerization initiators
