Q:what is petrolum ether? Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter naphtha and the heavier kerosene.(movie) specific gravity of between 0.6 and 0.8 ■Remember .Petroleum ether should not be confused with the class of organic compounds called ethers,which contain the -O-functional group. Likewise,benzine should not be confused with benzene.Benzine is a mixture of alkanes,e.g., pentane,hexane,and heptane,whereas benzene is a cyclic,aromatic hydrocarbon,C6H6
