Chromium potassium sulfate dodecahydrate Chemical Properties,Usage,Production

Chemical Properties

deep violet-red crystals

Uses

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

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 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.
