Potassium pyrosulfate Chemical Properties,Usage,Production

Chemical Properties

Colorless needles or white, crystalline powder or fused pieces. Soluble in water ( converted to potassium bisulfate).

Uses

Acid flux in analysis, laboratory reagent.

Uses

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.

Uses

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.

Flammability and Explosibility

Non flammable
