Litium karbida: Perbedaan antara revisi

There are a number of procedures employed, some that burn the sample producing [[carbon dioxide|CO₂]] that is then reacted with lithium, and others where the carbon containing sample is reacted directly with lithium metal.<ref>{{cite journal | author = Swart E.R. | title = The direct conversion of wood charcoal to lithium carbide in the production of acetylene for radiocarbon dating | journal = [[Cellular and Molecular Life Sciences]] | doi = 10.1007/BF02146038 | year = 1964 | volume = 20 | pages = 47}}</ref> The outcome is the same: Li₂C₂ is produced, which can then be used to create species easy to mass, like acetylene and benzene.<ref>[http://www.geo.unizh.ch/c14/ University of Zurich Radiocarbon Laboratory webpage]</ref> Note that [[lithium nitride]] may be formed and this produces [[ammonia]] when hydrolyzed, which contaminates the acetylene gas.
