Separating benzaldehyde from benzyl alcohol

Hi!

I've prepared some benzaldehyde from benzyl alcohol with calcium hypochlorite. Unfortunately my condenser has been broken and I can't use my distillation setup.

Does anyone have an idea how to separate what's left of benzyl alcohol from the aldehyde other than distillation?

The BzCHO forms an adduct with bisulfites what crystallizes easily and could be turned back to the aldehyde by bicarbonate or any other basic reagent.
