What is Potassium pyrosulfate?
Chemical properties
Colorless needles or white, crystalline powder or fused pieces. Soluble in water ( converted to potassium bisulfate).
The Uses of Potassium pyrosulfate
Acid flux in analysis, laboratory reagent.
The Uses of Potassium pyrosulfate
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.
The Uses of Potassium pyrosulfate
Potassium disulfite supported on silica may be used for the synthesis of ethyl pyruvate.
General Description
Potassium disulfite (Potassium pyrosulfate) has been synthesized from potassium hydrogen sulfate, via melting.
