I haven't tried this (yet) as I don't have any graphite electrodes, but I'm gonna start experimenting soon.
What would you anticipate happening? My assumption is that Cl2 will be released, then the alkali metal will react with the alcohol forming a metal alkoxide. Thats what I hope would happen at least as that would be an easy way to produce metal alkoxide salts. I don't know how well the various alcohols can solvate NaCl.
