Lithium imide is an inorganic compound with the chemical formula Li 2 N H. This white solid can be formed by a reaction between lithium amide and lithium hydride. [1] LiNH 2 + LiH → Li 2 NH + H 2. The product is light-sensitive and can undergo disproportionation to lithium amide and characteristically red lithium nitride. 2 Li 2 NH → LiNH 2 ...
Lithium amide or lithium azanide is an inorganic compound with the chemical formula LiNH 2. It is a white solid with a tetragonal crystal structure. [1] Lithium amide can be made by treating lithium metal with liquid ammonia: [2] 2 Li + 2 NH 3 → 2 LiNH 2 + H 2. Lithium amide decomposes into ammonia and lithium imide upon heating. [3]
The inorganic imide is an inorganic chemical compound containing an anion with the chemical formula HN 2−, in which nitrogen atom is covalently bonded to one hydrogen atom (as in lithium imide Li 2 NH and calcium imide CaNH). The other name of that anion is monohydrogen nitride.
Lithium hydroxide is another important compound that is used in air purification systems, as well as in the production of lithium greases and lubricants. Lithium chloride is used as a desiccant and in the production of lithium metal, while lithium sulfate is used in the production of fertilizers and as a reagent in chemical reactions
The result is a condensation reaction: [5] (RCO) 2 O + R′NH 2 → (RCO) 2 NR′ + H 2 O. These reactions proceed via the intermediacy of amides. The intramolecular reaction of a carboxylic acid with an amide is far faster than the intermolecular reaction, which is rarely observed.
It is commonly used as Li-ion source in electrolytes for Li-ion batteries as a safer alternative to commonly used lithium hexafluorophosphate. [3] It is made up of one Li cation and a bistriflimide anion.
Lithium peroxide (Li 2 O 2) in presence of moisture not only reacts with carbon dioxide to form lithium carbonate, but also releases oxygen. [174] [175] The reaction is as follows: 2 Li 2 O 2 + 2 CO 2 → 2 Li 2 CO 3 + O 2. Some of the aforementioned compounds, as well as lithium perchlorate, are used in oxygen candles that supply submarines ...
Lithium imide can also be formed under certain conditions. Some research has explored this as a possible industrial process to produce ammonia since lithium hydride can be thermally decomposed back to lithium metal. Lithium nitride has been investigated as a storage medium for hydrogen gas, as the reaction is reversible at 270 °C. Up to 11.5% ...
