The interesting thing you bring up, is that Propane would be a solid in
LOX.
Actually, no, propane is still liquid at the normal boiling point of LOX.
The good news is that they're mostly immiscible -- the two liquids won't
mix much. The bad news is that they're miscible *enough* that the result
is still explosive.
The one time I made a few milliliters of this mix, it seemed miscible
in that there was no obvious oil/water type separation at one
atmosphere. I should have done it in a test tube with a strong light
to look for an interface. But knowing how energetic this stuff is . .

One thing I left out of the description of the two-liter bottles is
that they capped them and let them warm up. A soda bottle at LOX
temperature (or LN2) will take a lot of pressure, probably upwards of
20 atmospheres. That may be enough to make the liquids fully
miscible.
If anyone wants to work with this stuff, do be careful. I know one
person who did and lost much of his hearing.
