화학적 성질

Cupferron is a creamy-white crystalline compound

용도

The reagent used to be considered as specific for iron(II) and copper(II). However, in the course of later analytical studies it turned out that cupferron forms complexes with several other metals too, even in acidic medium. It is used today primarily for the determination of copper(II), but it has proved suitable for the determination of aluminium(III), bismuth(III), iron(III), mercury(II), thorium(IV), tin(IV), titanium(III), vanadium(IV) and zirconium(IV) as well. Of these, the zirconium(IV) complex is the most stable. Cupferron precipitates zirconium(IV) quantitatively from aqueous media containing sulfuric acid.
The reagent gives a precipitate with most of the above metal ions even in strong mineral acidic medium. Only the aluminium(III) complex does not precipitate in the presence of mineral acids.
By means of cupferron many metal ions can be separated: thus, for instance, iron(III) can be separated from aluminium(III) and manganese(II) and titanium (IV), zirconium(IV) and hafnium(IV) from many other metal ions, etc. Though the reagent makes possible several separations, the precipitates are not exactly of stoichiometric composition (they almost always contain some excess of the ligand). Hence instead of being directly weighed, the precipitates are usually ignited and the metal oxide residues weighed.

일반 설명

Light yellow or cream-colored crystals or a brown crystalline solid. As a reagent in the separation of copper and iron.

공기와 물의 반응

Hygroscopic. Soluble in water.

반응 프로필

Cupferron may be sensitive to prolonged exposure to air. Incompatible with strong oxidizing agents, strong acids and strong bases. Forms unstable solutions with thorium, titanium and zirconium salts.

화재위험

Flash point data for Cupferron are not available; however, Cupferron is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by intravenous route. An eye irritant. Solutions with thorium salts are unstable explosives above 15°C. Solutions with titanium or zirconium salts are unstable explosives above 40℃. When heated to decomposition it emits very toxic NH3 and NOx. See also N-NITROSO COMPOUNDS and AMINES

잠재적 노출

Cupferron is used to separate tin from zinc, and copper and iron from other metals in the laboratory. Cupferron also finds application as a quantitative reagent for vanadates and titanium; and for the colorimetric determination of aluminum. The potential for exposure appears to be greatest for those engaged in analytical or research studies involving use of the chemical. Workers may also be exposed to the compound during manufacturing processes.

Carcinogenicity

Cupferron is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

Recrystallise it twice from EtOH after treatment with Norite and finally once with EtOH. The crystals are washed with diethyl ether and air dried, then stored in the dark over solid ammonium carbonate. A standard solution (ca 0.05M prepared in air-free H2O) is prepared daily from this material for analytical work and is essentially 100% pure. [Olsen & Elving Anal Chem 26 1747 1954.] It can also be washed with Et2O, dried and stored as stated. In a sealed, dark container it can be stored for at least 12 months without deterioration. 260nm (CHCl3). max [Marvel Org Synth Coll Vol I 177 1941, Elving & Olson J Am Chem Soc 78 4206 1956, Beilstein 16 IV 891.] Possible CARCINOGEN.

비 호환성

Forms unstable and possibly explosive compounds with thorium salts; titanium, zirconium.
