Description

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.
