CaC2 and alcohols

Tengo - 3-4-2003 at 20:05

I was wondering about the reactions of alcohols and CaC2...
Now the carbide ion being a stronger base than the alkoxide ion, should be able to rip off the hydrogen from the alcohol, forming C2H2...
With a simple alcohol like methanol or ethanol, I assume that a calcium alkoxide would form.

But what happens with ethylene glycol?
Could ethylene epoxide be formed?
C2H4(OH)2 + CaC2 => C2H4O + C2H2 + CaO ???
Or perhaps dioxane?
I really have no idea...
And then we have glycerol...

I think that the reaction would lead to acetylene <b>HCCH</b> and calcium salt of ethyleneglycol <b>Ca<sup>2+&nbsp;</sup>O<sup>-</sup>CH<sub>2</sub>CH<sub>2</sub>O<sup>-</sup>&l t;/b>, but NO WARRANTY! :)
