<\/p>\nLa formula chimica del nitrito di sodio \u00e8 NaNO\u2082, numero CAS: 7632-00-0. Si presenta come un cristallo di colore bianco-giallo chiaro. Presenta un'ottima solubilit\u00e0 in acqua e igroscopicit\u00e0. La soluzione acquosa \u00e8 debolmente alcalina con un pH di circa 9. \u00c8 facilmente solubile in ammoniaca liquida e leggermente solubile in solventi organici come etanolo, metanolo ed etere. Il nitrito di sodio ha un sapore salato e viene utilizzato per produrre sale da cucina artificiale. Nell'aria, il nitrito di sodio viene lentamente ossidato a nitrato di sodio (NaNO\u2082), un forte agente ossidante. Il nitrito di sodio \u00e8 soggetto a esplosioni a contatto con materia organica.<\/p>\n
Uso industriale: potresti aver bisogno di nitrito di sodio se operi nei seguenti settori.<\/p>\n
Industria alimentare: come additivo alimentare, il nitrito di sodio pu\u00f2 non solo colorare e mantenere freschi pesce e carne, ma anche inibire la crescita del botulismo.<\/p>\n
Usi medicinali: il nitrito di sodio ha un effetto significativo sulla dilatazione dei vasi sanguigni e sul miglioramento della circolazione sanguigna. Il nitrito di sodio \u00e8 anche utilizzato in farmaci vasodilatatori e broncodilatatori per uso umano o animale, e pu\u00f2 persino essere utilizzato per la disintossicazione dal cianuro.<\/p>\n
Uso chimico: il nitrito di sodio viene utilizzato per la conversione delle ammine in composti di diazonio. In laboratorio, il nitrito di sodio viene utilizzato anche per trattare l'eccesso di sodio azide.<\/p>\n
Altri campi di applicazione: composti nitrosi e altri composti organici; tintura e sbiancamento di tessuti in fibra; fotografia; agente anticorrosivo in laboratorio; additivo nel rivestimento dei metalli; produzione di gomma. La sua soluzione acquosa 10% \u00e8 utilizzata anche in galvanica.<\/p>\n
