What solids react to form liquids?
« on: 13/02/2016 17:41:54 »
I am trying to compile a list of substances that are solid under normal conditions (some flexibility here, but essentially 1 atm and 20 C) that react chemically to form exclusively products that are liquid under the same conditions (no gaseous or solid coproducts).

For instance:
C(s) + 2 S(s) → CS2 (l)
Na(s) + K(s) → NaK(l)
Ti(s) + 2 HgCl2 (s) → TiCl4 (l) + 2 Hg(l)

For the moment I am ignoring eutectic mixtures of molecular species that don't involve an actual chemical reaction, like: urea + choline chloride (https://en.wikipedia.org/wiki/Deep_eutectic_solvent)

Gallium and indium form a eutectic that melts about 15C
The mixture of SnI4 and SnBr4 that you would get by reacting Sn with IBr might be liquid if the SnI4 depresses the melting point of the SnBr4 far enough.

What do you plan to do with this magic?

Please disregard all previous signatures.

Wouldn't any thermoplastic solid raised to it's melting point produce a liquid? There are many of these.

Thanks!

I'm not planning on actually performing any of these reactions necessarily, but it came up during a discussion section I was leading, and I could only think of two examples off the top of my head.

I am interested in chemical reactions that transform solid precursors to products that are liquid at the same temperature. Of course we could come up with a very large set of solids that can melt :-)
