Acetaldehyde disposal


I've got a small bottle of about 1mL of unstabilized Acetaldehyde that's been sitting in a fridge for the past few months. I'm scared to touch the bottle, let alone open it.

Shall I just grab it with tongues and throw it in a fire?

That small amount shouldn't be too big of a boom.
As for proper disposal, complete combustion.

For the record, I would not recommend touching it with your tongue. :P


I see no reason why anyone would be storing acetaldehyde. But then, I have only ever made it as a byproduct of another reaction.
It burns very readily. I poured mine out onto a concrete path and tossed a match at it. About 40mL from memory, but it would not have been pure. It was all over within a minute or so.

Just 1 ml? Open the bottle outside, and pour it out on a piece of paper tissue. Within seconds it will be gone (evaporated). Leave the bottle open, to get rid of an adhering film of liquid on the inside.
