Diethyl ether is extremely flammable and may be explosive. Since ether is heavier than air it can collect low to the ground and the vapour may travel considerable distances to ignition sources, which need not be an open flame, but may be a hot plate, steam pipe, heater etc.
Best Answer: Petroleum ether is a mixture of two hydrocarbons, Hexane which is liquid and a certain amount of Propane, which is a hydrocarbon gas soluble in Hexane.This lowers the boiling point of the mix below that of Hexane. believe it is about 30 dollars a gallon.

However it is also twice as inflammable and can even decompose into explosive peroxides as it ages.
