Is there a chemist in the forum who knows about the residual impurities left behind (on or in the metal) from storing toluene in a barrel or drum?
I'm making a smoker with a 55 gallon drum which was used once to store toluene (new from the factory) and then discarded. I would like to hear from someone with a background in chemistry, who knows about the effects of using a barrel like this for smoking. What would the purging process be, what contaminates are left after evaporation & several months of sitting in the sun with openings for airflow allowing oxygen to interact with the interior surface.
Please note, I asked for a chemist for an answer to this question (a scientist with the right background would be helpful also). Hear-say, opinions, & uninformed guesses about this question aren't really what I'm looking for & won't be helpful. I have a call into a manufacturer already, but haven't heard back yet so I'm wondering about someone from the forum who has a background in chemistry who can help.
