Active alumina ball used for aqueous hydrogen peroxide
Crystal form: - AL2O3
Molecular formula: AL2O3nH2O(0
Molecular weight: 102< Molecular weight≤ 117
Physical character:
White, ball shaped, porous substance; Innocuity, insipidity, scentlessness, insoluble in water and organic solvent such as ester, hydrocarbon, mellow. Strong points: No powder, no softness, high degree of clarity, long life span, degradation and regeneration ability for AQ derivatives, the special sorbent for aqueous hydrogen peroxide produced by AQ method. Except adsorption of alkali in working liquid, the item have strong regeneration ability to hydrogenation degradation substance. It can transform degradation substance increased in hydrogenation reaction into effective anthraquinone, guarantee the stability of effective anthraquinone, make for the process of oxygenation reaction, reduce the addition of anthraquinone, save the operating cost. At the same time, in consideration of regeneration, aqueous hydrogen peroxide alumina guarantee good mechanical performance. The activity after regeneration change little.
Special sorbent active ball for aqueous hydrogen peroxide production, the granularity can be customed according to the requirement.
