Kent: Anthony's advice to contract with a reactive chemicals disposal firm is excellent. I would add the following couple of details to it. What the disposal firm needs to do is remotely open the can and add a suitable solvent (ethanol is probably a good choice) then reseal the can and dispose as a flammable liquid lab pack, carefully re-labelling it according to your local requirements. I don't know if I'd attempt to bulk it with other flammable liquids at that point. If the container comes apart during the remote opening, well, you've solved your problem, haven't you? Onyx Environmental is a firm we've used - I have no financial or personal interest in Onyx. Hope this helps, Debbie Debbie M.
