The process to produce calcium carbide is energy intensive
Theres has to be an easier way
magnesium with sodium carbonate seems doable in forming sodium carbide
Seemingly cheapest and otc method
But the reaction of magnesium and lithium carbonate
Seems to make lithium carbide
Magnesium and sodium carbonate used first then if that works
Aluminum and sodium carbonate heated together causing the aluminum to reduce the sodium carbonate to sodium carbide

I assumed that the solid was sodium intercalated into carbon, and that the gasses on contact with water were hydrogen, but these were merely
assumptions.AJKOER - 2-1-2017 at 05:08
On a small scale, Berthelot, per Wikipedia on C2H2 (see https://en.m.wikipedia.org/wiki/Acetylene ), is said to have obtained acetylene directly by passing hydrogen between the poles of a carbon arc.
Likely radical reactions:
H2 + e = H· + H·
C + H· ?→ CH·
CH· + CH· ?→ C2H2
Similarly on a small scale, I would speculate on a theoretically possible direct path to C2H2 (likely mixed with other products depending on the
embodiment) and its salts, may be to react an excess of the vinyl radical with simultaneously generated hydroxyl radicals per a radical reaction
assuming hydrogen abstraction:
C2H3· + OH· ?→ C2H2 + H2O
But, not sure if the carbon triple bond would be actually created here!
