No. 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.

Even at 300PSI?

Acetylene has a critical pressure (905 PSI), at least theoretically. But as
you know, acetylene is very unstable at high pressures (that's why it is
stored dissolved in acetone in cylinders). So the critical pressure is never
reached in practice.
