Petroleum ether, also known as '''benzine''', is a group of various volatile, highly flammable, liquid Hydrocarbon mixtures used chiefly as Nonpolar Solvents . Petroleum ether is obtained from Petroleum refineries as the portion of the distillate which is intermediate between the lighter Naphtha and the heavier Kerosene . It has a specific gravity of between 0.6 and 0.8 depending on its composition. 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. LIGROIN Ligroin is a refined Saturated Hydrocarbon Petroleum Fraction similar to petroleum ether used mainly as a Laboratory Solvent . It predominantly consists of C7 through C11 in the form of about 55% Paraffin s, 30% monocycloparaffins, 2% dicycloparaffins and 12% alkylbenzenes. It is Nonpolar . Generally laboratory grade ligroin boils at 60 to 90 ° C . |
