Discovery two main applications of 2-ethylanthraquinone (Cas 84-51-5): synthesis of hydrogen peroxide via antraquinoneand formulators of anthraquinonic dye where 2EAQ is an additive for strengthen the color for Italian and Finland endusers
18 Dec 2019
A new synthesis method of hydrogen peroxide was investigated by the photoreduction of 2-ethylanthraquinone (AQ) in water-insoluble organic solvents. Through optimizing the photoreduction condition including solvent, atmosphere and irradiated time, the photolysis system of 1,3,5-trimethylbenzene/trioctyl phosphate (3:1) solvent mixture under oxygen atmosphere was found to give a high yield of hydrogen peroxide. Furthermore, the formation mechanism of hydrogen peroxide was proposed, i.e. photoreduction and subsequent oxidation of AQ. The photoreduction of 2-ethylanthraquinone undergoes the hydrogen abstraction from solvent to form the anthrahydroquinone, which is subsequently oxidized by oxygen to give hydrogen peroxide.

Our principals have studied, for many years, all the steps of the all-TETRA process , we have studied and optimized in particular: (i) the reactor of tetra-hydroanthraquinone hydrogenation, (ii) the oxidizing reactor, (iii) the active quinones regeneration, (iv) the start-up procedure for a new industrial plant. Our studies have been made following the mentioned reactors and operations respectively in: laboratory plants, pilot plants and industrial plants.

As our associated manufacturer of 2-ethylanthraquinone with the largest scale in China, with annual output of 2,000 tons crude products and 1,500 tons of refined products , our 2-Ethylanthraquinone is refined product with higher purity 99% than other suppliers in china . We have REACH full registered ,we usually export to Italy , Finland , America , and Southeast Asiamarket , many of our customers come from paper or dye industry in H2O2 production. Some of our Italy clients are as formulators of anthraquinonic dye where 2EAQ is an additive for strengthen the color.
