WebAs hydrogen peroxide is less stable at high pH than under acidic conditions, [NH4]OH (pH c. 11.6) also accelerates its decomposition. At higher pH, H2O2 will decompose violently. … WebThe difference between this “apparent pH” and “real pH” varies from about 1.3 pH units for 35% H 2 O 2 to about 2.7 pH units for 70% H 2 O 2. Correcting for apparent pH deviations, …
WebLignin oxidation by bacterial dye-decolorizing peroxidase enzymes requires hydrogen peroxide as a co-substrate, an unstable and corrosive oxidant. We have identified a glycolate oxidase enzyme from Rhodococcus jostii RHA1 that can couple effectively at pH 6.5 with DyP peroxidase enzymes from Agrobacterium sp. or Comamonas testosteroni to ...
WebProduction. Peracetic acid is produced industrially by the autoxidation of acetaldehyde:. O 2 + CH 3 CHO → CH 3 CO 3 H. In the presence of a strong acid catalyst, such as sulfuric acid, acetic acid and hydrogen peroxide produce peracetic acid: H 2 O 2 + CH 3 CO 2 H ⇌ CH 3 CO 3 H + H 2 O.
