Chromium hydroxide, a gelatinous, polymeric inorganic powder, is amphoteric in nature. It reacts as an acid as well as a base. On heating, it decomposes to chromic oxide. The molecule is largely used in cosmetics and tanning industries.
Chromium hydroxide is produced by reaction of chromic chloride with aqueous ammonia.
|Cosmetics||Chromium hydroxide is used as a green pigment. In this usage, toxicity of chromium is not regarded as health hazard.|
|Tanning Industry||A major part of the tanning industry use trivalent chromium salts for tanning and the main compound is chromic hydroxide.|
|Catalyst||The oxide is particularly used as a catalyst in chemical processes such as:|
– Dehydrogenation of alcohols
– Hydrogenation of olefins
|Other uses||– As mordant in textile industries, the lakes formed with this product renders extreme light and washing fastness to the fabric.|
– A feeble application in proteomic research is also cited.
|Appearance||–||Grey greenish to grey-blue powder|
|Purity||%||70 – 80|
The product is stored at ambient temperature.
