      solvent inert to CaC2?  Bookmark   

What solvents are inert towards CaC2?  More specifically, one that acetamide would be fairly soluble in.

Well, I didn't really mention it in the question but I was asking this so that I could start forming a procedure for dehydrating acetamide to acetonitrile.  So if anybody has thoughts on that too, I'd like to hear them.

      Solvents compatible with calcium carbide  Bookmark   

You want a solvent not containing any acidic hydrogens or other functional groups sensitive to bases. Such solvents include hydrocarbons (like hexane/toluene) and ethers (THF/Et2O).

Chlorinated hydrocarbons (DCM, chloroform) might react, so don't use them just to be safe. Esters, alcohols and ketones and any solvents not properly dried are directly unsuitable.

Would CaC2 dissolve in benzaldehyde, forming (after acidification) 1,4-diphenyl-1,4-dihydroxy-2-butyne?
CaC2 + 2Ph-CHO -> Ph-C(OH)-C---C-C(OH)-Ph

Just a thought... C22- being such a strong base, that it would add to the carbonyl and making a hydroxy... SN2 basically... Well... a nucleophile attack anyway...
If CaC2 won't dissolve in benzaldehyde, then this wouldn't work. But perhaps with another solvent...?

Maybe you could heat acetamide and CaC2 together without a solvent.  Try a small amount in a test tube.  You could connect a one hole rubber stopper and 90 degree piece of glass tubing to the test tube and then connect a condenser to it and see if you can distill off any CH3CN.

The hardest thing to explain is the obvious
