Sicherheit

NIOBIUMCHLORIDE Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften

Brown-black crystal needles; pure brown in transmitted light.
Decomposes on exposure to air and moisture (color change first to black, then to white). Dissolves in a small amount of H2O and in dilute hydrochloric acid, giving a dark-blue solution.

Verwenden

NIOBIUMCHLORIDE is used as reductively couples imines and nitriles.

synthetische

Reduction of NbCl5 with H2 at 2 atm. (generated when the tube is filled at STP, sealed and then heated). The reaction does not go to completion and NbCl5 and NbCl4 must be separated by sublimation.

l?uterung methode

NIOBIUMCHLORIDE is Purified by filter and wash with THF and dry under vacuum.

Vorsichtsma?nahmen

Niobiumchloride is corrosive; moisture sensitive. Use in a fume hood.
