염화크롬(Ⅲ) C화학적 특성, 용도, 생산

화학적 성질

Chromic chloride is a highly corrosive, Blue or greenish to black crystalline solid.

용도

Supplement(trace mineral).
Chromium(III) chloride and chromium(III) sulfate have been used as dietary supplements (approved for themanufacture of foods for particular nutritional uses and in food supplements in the European Union), whereas the organic chromium(III) complexes chromium picolinate and nicotinate are not approved in the European Union but find widespread uses (e.g. in the USA) inmultivitamin, multimineral products (Riihimaki & Luotamo, 2006).They are also marketed for weight loss purposes and athletic supplements.

공기와 물의 반응

The rate of solution for water is extremely slow, pH of 0.2 M. aqueous solution is 2.4.

반응 프로필

When heated to decomposition, CHROMIUM (III) CHLORIDE emits toxic fumes of chlorine containing compounds. Violent reaction with lithium, nitrogen. Incompatible with strong oxidizers. [EPA, 1998].

위험도

A poison.

건강위험

CHROMIUM (III) CHLORIDE displays high dermal toxicity, and moderate oral toxicity.

Safety Profile

Poison by skin contact, inhalation, and intraperitoneal routes. Experimental teratogenic and reproductive effects. Human mutation data reported. Questionable carcinogen. Reacts violently with lithium under nitrogen atmosphere. When heated to decomposition it emits toxic fumes of Cl-.

잠재적 노출

Chromic chloride is used for production of solutions of basic chlorides and as a catalyst for polymerization of olefins and other organic reactions; in chromizing; in the manufacture of chromium metal and compounds; as a textile mordant; in tanning; in corrosion inhibitors; and as a waterproofing agent. A nutritional supplement.

운송 방법

UN1759 Corrosive solids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required. UN1760 Corrosive liquids, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.

Purification Methods

Sublime the chloride in a stream of dry HCl. Alternatively, the impure chromic chloride (100g) is added to 1L of 10% aqueous K2Cr2O7 and several millilitres of conc HCl, and the mixture is brought to a gentle boil with constant stirring for 10minutes. (This removed a reducing impurity.) The solid is separated and washed by boiling with successive 1L lots of distilled water until the wash water no longer gives a test for chloride ion, then dry it at 110o [Poulsen & Garner J Am Chem Soc 81 2615 1959, Hein & Herzog in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1338 1965].

비 호환성

Reacts with water and strong oxidizers. Contact with strong acids or acid fumes may produce highly toxic chloride fumes. May attack certain steels, causing pitting attack and stress corrosion

폐기물 처리

Precipitate as chromium hydroxide. Dewater the sludge and dispose of the compacted sludge in single-purpose dumps
