Montegue, i looked up an MSDS for mentone, and it is not very volatile at all, has a relatively high boiling point, and is used in perfumery and flavorings. although it is used as a pesticide at times, I would have to intentionally ingest some in order for it to effectively toxify me. I believe you have a misunderstanding of what "dangers" exist here, which are very similar to the dangers of many standard organic reactions. My greatest worry would be the chlorine gas emitted from the sodium hypochlorite, but as in i plan to wear a respirator for this experiment, if done carefully should not be too risky.
