Chemische Eigenschaften

crystal(s) white powder(s); decomposes in water, evolves acetylene when dissolved in acid [HAW93]

synthetische

Lithium carbide, Li2C2, may be prepared by the direct combination of lithium and carbon at about 1000°C or by the reaction of lithium metal with acetylene in liquid ammonia. The latter process first yields lithium acetylide, LiC=CH, which decomposes to lithium carbide. The conversion to the carbide is incomplete, however . A convenient laboratory preparation of lithium carbide may be carried out by bubbling acetylene into a solution of n-butyllithium in hexane. The precipitated carbide may be filtered from the reaction mixture, washed, and dried. Lithium carbide is ionic and yields acetylene on hydrolysis.

Vorsichtsma?nahmen

Dilithium Acetylide is highly moisture sensitive; very short exposure to air under good ventilation is allowed. Use of a freshly prepared solution is advised. Use in a fume hood.
