Pentacloruro de niobio

Descripción:

Pentacloruro de niobio (NbCl5) es un compuesto inorgánico caracterizado por su forma sólida de color marrón oscuro a negro a temperatura ambiente. Es una sustancia altamente reactiva e higroscópica, lo que significa que absorbe fácilmente la humedad del aire. Pentacloruro de niobio es conocido por su capacidad para actuar como un ácido de Lewis, lo que lo hace útil en varias reacciones químicas, particularmente en la síntesis de compuestos que contienen niobio. Tiene una estructura cristalina compleja y puede existir en diferentes formas polimórficas. El compuesto se produce típicamente a través de la cloración del óxido de niobio o del metal de niobio. Debido a su reactividad, debe manejarse con cuidado, ya que puede reaccionar violentamente con agua, liberando ácido clorhídrico y óxido de niobio. En términos de aplicaciones, NbCl5 se utiliza en la producción de aleaciones de niobio y como catalizador en la síntesis orgánica. Las precauciones de seguridad son esenciales al trabajar con este compuesto, ya que puede representar riesgos para la salud si se inhala o si entra en contacto con la piel.
