Descripción

Sodium cyanide is used as a starting material for the preparation of Reissert compounds and cyanogen bromide, cyanuric chloride and cyanogen chloride. It acts as a catalyst for the aminolysis of esters to primary amides. Furthermore, it is used for fumigation, electroplating, extracting gold and silver in mining industry. In organic synthesis, it is involved in the cyanation reaction of alkyl halides under phase transfer conditions.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El cianuro de sodio se utiliza como material de partida para la preparación de compuestos de Reissert y bromuro de cianógeno, cloruro cianúrico y cloruro de cianógeno. Actúa como catalizador para la aminólisis de ésteres a amidas primarias. Además, se utiliza para fumigación, galvanoplastia, extracción de oro y plata en la industria minera. En la síntesis orgánica, participa en la reacción de cianación de los haluros de alquilo en condiciones de transferencia de fase.

Solubilidad
Soluble en agua, amoníaco, metanol y etanol. Ligeramente soluble en dimetilformamida. Insoluble en dimetilsulfóxido.

Notas
Higroscópico. No almacenar cerca de ácidos. Incompatible con agentes oxidantes fuertes y dióxido de carbono.
