Nitrite water boiling stability
Webbtert -Butyl nitrite is an organic building block widely used in various organic transformations such as oxidation, diazotization, nitrosation, nitration, oximation, N -synthon, and miscellaneous reactions [ 1]. Application tert -Butyl nitrite can be used as a reactant to synthesize aryl diazonium salts via diazotation [ 2]. Packaging WebbLithium nitride is a compound with the formula Li 3 N. It is the only stable alkali metal nitride. The solid has a reddish-pink color and high melting point. [1] Preparation and handling [ edit] Lithium nitride is prepared by direct combination of elemental lithium with nitrogen gas: [2] 6 Li + N 2 → 2 Li 3 N
