Application | hydrogenation in solvent to produce 2-ethylhydroanthraquinone, upon re-oxidation, 2-ethylanthraquinone and hydrogen peroxide are regenerated and this reaction is used industrially to produce hydrogen peroxide. It is prepared from phthalic anhydride and ethylbenzene by the reaction of 1, 4-naphthoquinone with 2-ethyl-1, 3-butadiene by Diels-Alder diene synthesis and dehydrogenation reaction. It is used in the production of hydrogen peroxide and as a dye intermediate, and also as a photosensitizer for photosensitive resins, photocurable resin catalysts, photodegradable films, coatings and photopolymerization initiators. |
Application | is a catalyst for producing hydrogen peroxide, a photosensitizer for a photosensitive resin, etc. used in the manufacture of hydrogen peroxide, dye intermediates, photocurable resin catalysts, photodegradable films, coatings and photopolymerization initiators |
