Useful:

• Uses: Acid flux in analysis, laboratory reagent. Potassium disulfate (K2S2O7) can be used: As a salt catalyst for the conversion of hemicellulose into reducing sugars such as xylose and galactose by mechanocatalysis . In the preparation of diacylbenzenes via Pd-catalyzed decarboxylative acylation of aromatic ketones with oxocarboxylic acids. As an oxidant for the preparation of monosubstituted triazoles from aryl azides and propargyl alcohol using Ag2O as a catalyst. Potassium disulfite supported on silica may be used for the synthesis of ethyl pyruvate.
