Hi Msummers,
Ignition and boiling are quite different processes. Most things have a spontaneous ignition point, where they get hot enough that a mixture of vapour and air would catch fire without a spark or flame. Gasoline ignites at well over 200 degrees.
To boil gasoline, you need to use a heat source that doesn’t involve an open flame, or the vapour might spread to the flame and ignite. Don’t use a microwave either, as sparking can be just as bad.
You;d need to do this in an inert atmosphere with no oxygen, e.g argon or nirogen… the fact that gasoline is so volatile (evaportes easily) you’d require very little heat to ‘boil’ it.
Seems like most gasoline has a boiling point in the range of about 37°C – 200°C . However, we don’t normally see it boil. Its got a low vapor pressure so typically it just evaporates. However the internets tell me that if you were using a gasoline you bought during the winter it might be possible. The gasoline we buy changes by season: winter gasoline has a higher vapor pressure and contains much more light material such as butane and isobutane. I am not sure if this is entirely true, but if you were using that in warmer weather it might possibly boil, even at standard atmospheric pressure.
