Lithium hydride is an inorganic compound with the formula Li H.This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting point, and it is not soluble but reactive with all protic organic solvents.
Melting point TG data DSC IR spectra NMR data Solubility References Li(TMHD), Lithium tetramethylheptanedionate, C 11 H 19 LiO 2: 22441-13-0 Decomposes at low pressure and room temperatures, [1] stable under N 2 or Ar in sealed contanier and decomposes slowly in contact with moist air and rapidly in contact with water.
The melting point of a substance is the point where it changes state from solid to liquid while the boiling point of a substance (in liquid state) is the point where the vapour pressure of the liquid equals the environmental pressure surrounding the liquid [102] [103] and all the liquid changes state to gas. As a metal is heated to its melting ...
Other method for production of Li 2 C 2 is heating of metallic lithium in atmosphere of ethylene. Lithium hydride is a coproduction: 6 Li + C 2 H 4 → Li 2 C 2 + 4 LiH. Lithium carbide hydrolyzes readily to form acetylene as well as Lithium hydroxide: Li 2 C 2 + 2 H 2 O → 2 LiOH + C 2 H 2. Lithium hydride reacts with graphite at 400°C ...
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
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% ...
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Lithium borohydride (LiBH 4) is a borohydride and known in organic synthesis as a reducing agent for esters. Although less common than the related sodium borohydride, the lithium salt offers some advantages, being a stronger reducing agent and highly soluble in ethers, whilst remaining safer to handle than lithium aluminium hydride.
