Descripción

Ammonium hydroxide is widely utilized as a leavening agent or acidity regulator in food production. It serves as a precursor to some alkyl amines and is also used in the tobacco industry for flavor enhancement and as a processing aid. During furniture making, it combines with tannic acid and is used to darken or stain wood by making it iron salts. In chemical laboratories, it used for qualitative inorganic analysis, as a complexant and as a base. It is used to clean gold, silve, and platinum jewelry. It is an active component of Tollens' reagent (consisting of a solution of silver nitrate and ammonia) and is used to determine the presence of aldehyde or alpha-hydroxy ketone functional groups.

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 hidróxido de amonio se utiliza ampliamente como agente leudante o regulador de la acidez en la producción de alimentos. Sirve como precursor de algunas alquilaminas y también se utiliza en la industria tabacalera para mejorar el sabor y como ayuda en el procesamiento. Durante la fabricación de muebles, se combina con el ácido tánico y se utiliza para oscurecer o teñir la madera convirtiéndola en sales de hierro. En los laboratorios químicos se utiliza para el análisis cualitativo inorgánico, como complejo y como base. Se utiliza para limpiar joyas de oro, plata y platino. Es un componente activo del reactivo Tollens′ (consistente en una solución de nitrato de plata y amoníaco) y se utiliza para determinar la presencia de grupos funcionales de aldehído o alfa-hidroxicetona.

Solubilidad
Miscible con el agua.

Notas
Incompatible con el cobre, el hierro y el zinc.
