... Acetylene sublimes from solid to gas at -84 C. It is what's called
a "reluctant" liquid in that you'll never normally find it in the liquid state.

Hmm. Extremely non-polar molecule. No vanderwalls forces I guess.

Normally, the acetylene is dissolved in acetone in the tank. Acetone
freezes at -94.7 C.

Ever make ethanol ice cubes?
