I find this really hard to believe. Suppose I want to throw a Molotov cocktail for shits and giggles and own a vacant lot with a short brick wall. Why can't I Molotov my own wall?
They really are illegal in the USA. However, if you have acres of land with no neighbors to complain (and don't manage to set the countryside on fire in the process) and don't post the videos on the internet, law enforcement probably has more important things to to be concerned with. That still doesn't make it legal, just unlikely you'd get caught.
Any volatile hydrocarbon should work well. Gasoline certainly works. Acetone might be particularly impressive given that it vaporizes so readily.
That would probably make a large, albeit brief, fireball worthy of Michael Bay. As an improvised incendiary weapon though, the idea generally is to have the fuel stick to the target and burn for a prolonged period. It's not hard to figure out which additive would accomplish that goal, but I'm speaking purely from the standpoint of this is just information that's freely available on the internet. I think the general idea is that if you've figured out how to make the kind of cocktail that is served up for serious cases of civil unrest, then you probably also have enough sense to know not to actually do it. Which is pretty much the same thing the chemists over on Reddit say about making meth.
