Help cleaning some calcium carbide
I got some calcium carbide from a store (haven't seen it on shelves in ages), in the form of groundhog/mole repellent. It's technical grade,
gray-black in color, but it also contains 2-undecanone and citriodiol and probably other stuff not mentioned on the label. Since I don't want the
repellents interfering in my reactions, what could I use to remove them?
I'm looking for something OTC here, BTW.

Pretty much any anhydrous organic solvent can do the job: acetone, ethyl acetate, toluene, petroleum ether. Alcohols react with CaC2 yielding calcium
alcoxides.
Calcium phosphides will still remain in the powder, because it is just as insoluble as calcium carbide.

I'd grind it fairly fine before proceeding. I got some from Germany and it is pea gravel sized chunks. I doubt that the solvents would do a good job
penetrating the chunks.
