Chromium nitrate is used in the manufacture of alkali metal-free catalysts and in preservation. It is used in the preparation of chrome catalysts, in textile printing operations, and as a corrosion inhibitor. Chromium(III) nitrate as a source of chromium is added to food supplements for nutritional purposes .m?gliche Exposition

UN2720 Chromium nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizerl?uterung methode
The pure deep violet nonahydrate salt is best prepared freshly from pure recrystallised (3 times) chromium (VI) trioxide and pure nitric acid. A solution is prepared by dissolving 1g of CrO3 in 3mL of H2O and 2mL of pure HNO3, and carefully, with stirring (behind a screen) pure MeOH (0.5-1.0mL) is added dropwise carefully (shield) with cooling to avoid a violent reaction. A bluish colour develops as Cr(VI) is reduced to Cr(III). When this solution is diluted to 130,000ppm of the salt, analysis detected by ICP/MS gave the following trace elements (ppm in brackets): Sr (33), Na (3.5), Mo, Ni, Cu, Si and Mg (0.13 each), Se, Zn, Al (0.026 each), Ti (1.5), Fe (4.9), Co (0.07), Sn (0.065), Ba (0.013 and W (0.078). Evaporation of the methanolic solution in high vacuum over CaCl2 eventually yields pure deep violet rhombic crystals of chromium (III) nitrate nonahydrate. An aqueous solution of this salt becomes green on heating but reverts to the violet colour on cooling.Inkompatibilit?ten
