    Hi. Looking for a substance that melts at around -50'C, boils about 75'C, is not harmful to the environment, and doesn't act (burn/oxidize) with air. Let me know or point me in the right direction. Temperatures can vary. Just looking for something that boils easily and won't freeze. Thanks, Murray.

    Look at perhaps, some organic solvents; just off the top of my head, maybe, carbon tetrachloride? jocular

    Eek. Carbon tetrachloride is pretty toxic. Most organic solvents are environmental hazards, and some halocarbons have their own problems (remember the ozone layer).

    (Sorry, not to have a more positive contribution...)

    Well, at -23 M.P. and 76 B. P., I have to say I pulled a close guess out of my ass! we were not asked to evaluate potential dangers, toxicity, etc., of the substance choice, only "is there a substance".

    Carbon Tet was used very extensively as the active agent in fire extinguishers for decades. It is very heavy, stinks like hell, potentially carcinogenic, non-combustible.

    Other dangerous and toxic substances are quite readily available: gasoline, methanol, mercury, barium (doctors make you swallow it), Fruit and vegetable cans lined with Bisphenol A emitting coatings, sodium nitrite-laced preserved meats, should I be "askeered" of them? jocular

    Thanks, Assended. Got the boiling points. That's a great start. Also. Need the melting point. Then I can try to narrow it down to environmentally friendly and then reaction to air. Please post if you find any more great ideas. Thanks again.
