Petroleum ether, also known as benzine, X4 or Ligroin, is a group of various volatile, highly flammable, liquid solvents.

Petroleum ether is obtained from petroleum refineries as the portion of the distillate which is intermediate between the lighter kerosene. It has a specific gravity of between 0.6 and 0.8 depending on its composition.

Benzine should not be confused with ethers, which contain the -O- functional group.

During the Second World War some extermination camps experimented to kill people with benzine injections.[1]
