CAS 7446-08-4: Dióxido de selenio
Descripción:
Dióxido de selenio (SeO2) es un compuesto químico caracterizado por su estructura molecular, donde el selenio está en un estado de oxidación +4. Aparece como un sólido cristalino blanco o amarillento y es conocido por su naturaleza higroscópica, lo que significa que absorbe fácilmente la humedad del aire. Dióxido de selenio es soluble en agua, formando ácido selenioso, y también puede disolverse en disolventes orgánicos. Este compuesto se utiliza principalmente en la síntesis orgánica, particularmente en la oxidación de alcoholes a compuestos carbonílicos y en la preparación de materiales que contienen selenio. Presenta propiedades tóxicas, lo que requiere un manejo cuidadoso debido a sus posibles riesgos para la salud, incluyendo irritación respiratoria y otros efectos sistémicos tras la exposición. Además, Dióxido de selenio puede actuar como un ácido de Lewis, participando en varias reacciones químicas. Su reactividad y capacidad para formar varios compuestos de selenio lo convierten en una sustancia importante tanto en entornos industriales como de laboratorio. Se deben observar las medidas de seguridad adecuadas al trabajar con Dióxido de selenio para mitigar sus efectos tóxicos.
