Chromium potassium sulfate dodecahydrate Chemical Properties,Uses,Production

Chemical Properties

deep violet-red crystals

Uses

Chromium(III) potassium sulfate dodecahydrate [KCr(SO₄)₂.12H₂O] has been used for the dissolution of gelatin in various studies.
It may be used as a starting material in the synthesis of quasi-monodisperse spherical core-shell particles of Cr/α-Cr₂O₃ to be used as solar absorbers.

Uses

Chromium potassium sulfate dodecahydrate is used in method for synthesizing metal-organic terephthalate structure MIL-101 (Cr).

Uses

Chromium potassium sulfate dodecahydrate is used in preparation of chromium standard solutions.

General Description

Chromium(III) potassium sulfate dodecahydrate (Potassium chromium(III) sulfate dodecahydrate, Chrome alum) is a violet colored solid. It has been synthesized by reacting sulfur dioxide with potassium dichromate (diisolved in sulfuric acid) at -38°C. It is widely used chemical in dyeing and textile industry.

Purification Methods

Crystallise it from hot water (2mL/g) by cooling.
