Application
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.
