Polymerization of nitrogen in sodium azide
WebDec 14, 2024 · Sodium azide (NaN 3) is a colorless or white crystalline salt with diverse medicinal and industrial applications.Recently, NaN 3 is considered as an inexpensive and valuable source of nitrogen in organic synthesis for the construction of N-heterocycles, amines, nitriles and amides due to extremely good nucleophilicity of the azide anion.. … WebOn heating Sodium azide around 400°C , it decomposes and releases large amount of nitrogen gas. About 130 g of the Compound on heating releases (3 x 22.4)=67.2 litres of nitrogen gas, which is the main reason for explosion. As mentioned earlier it also releases large amount of heat energy. I have made this in my work as well as sodium ethoxide.
