Hazards Summary
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Vanadium is absorbed mainly via inhalation, though small amounts can be absorbed through the skin and gastrointestional tract. It is rapidly distributed in the plasma, mainly to the kidney, liver, lungs, heart, bone, where it tends to accumulate. With the help of cytochrome P-450 enzymes, it can interconvert between its two oxidation states, vanadyl (V+4) and vanadate (V+5). Both states of vanadium can reversibly bind to transferrin protein in the blood and then be taken up into erythrocytes. Vanadium is excreted mainly in the urine. (L837)
Uses & manufacturing
Uses
Used in the preparation of vanadium dichloride and organovanadium compounds; [Hawley] Used as a catalyst in the production of EPDM rubber and polyethylene; [Ullmann]
Vanadium(III) chloride is a common precursor to other vanadium(III) complexes.
General Manufacturing InformationVanadium chloride (VCl3): ACTIVE
Applications
UsesPreparation of vanadium dichloride and organovanadium compounds.
UsesVanadium(III) chloride has been used as a catalyst for Biginelli condensation. As a reducing agent, it is capable of converting nitrate to nitrite in water samples, allowing for the direct detection of nitrates.
General DescriptionVanadium(III) chloride is a crystalline solid with variable oxidation states. It is widely used as a catalyst in organic synthesis, polymerization processes, and redox batteries. It acts as a reducing agent.
Preparation methods
Vanadium trioxide powder (2.1 g) and 8.5 ml of pure SOCl2 are placed in a bomb tube about 1.5 cm. in diameter, and the sealed tube is heated for 24 hours at 200℃. The tube is cooled to below 0℃ (in order to lower the SO2 vapor pressure) and is then opened to allow SO2 to escape. Then the tube contents are flushed out, under anhydrous conditions, into a small flask, using some SOCl2 for this purpose (the SOCl2 is then removed by vacuum distillation). The VCl3 residue is washed several times with very pure CS2 to remove traces of S2Cl2, and then thoroughly vacuum-dried at 80℃. Fine crystals of dark-violet VCl3 are obtained in nearly quantitative yield.
