Chemical compound
Lithium carbide, Li2C2, often known as dilithium acetylide, is a chemical compound of lithium and carbon, an acetylide. It is an intermediate compound produced during radiocarbon dating procedures. Li2C2 is one of an extensive range of lithium-carbon compounds which include the lithium-rich Li4C, Li6C2, Li8C3, Li6C3, Li4C3, Li4C5, and the graphite intercalation compounds LiC6, LiC12, and LiC18.
Li2C2 is the most thermodynamically-stable lithium-rich carbide[3] and the only one that can be obtained directly from the elements. It was first produced by Moissan, in 1896[4] who reacted coal with lithium carbonate.
Li2CO3 + 4 C → Li2C2 + 3 CO
The other lithium-rich compounds are produced by reacting lithium vapor with chlorinated hydrocarbons, e.g. CCl4. Lithium carbide is sometimes confused with the drug lithium carbonate, Li2CO3, because of the similarity of its name.
