Physical Properties: This product is a white, spherical porous material with the property of nontoxic, odorless, tasteless and insoluble in water, esters, hydrocarbons, alcohols, organic solvents, and it is not powdering and softening in water and alkali.As the high clarity, long usage time and strong ability of biodegradation and regenration for anthraquinone derivative,it is the special adorption for hydrogenperoxide production made by anthraquinone method. Besides of adorpting the alkali in fluid, it has the high regeneration capacity for hydrogenation degradation products, and it could transfer the hydrogenation degradation to anthraquinone to insure the stability of the general effective antheaquinone. So it can save the cost. Moreover, considering the need of regeneration ,the alumina for hydrogenperoxide can insure the excellent mechanism performance as the small changes in activity after regeneration.
