According to their corresponding MSDS, most commercially offered petroleum benzine solvents consist of parrafins ( alkanes ) with chain lengths of C5 to C9 ( " i . e . " n-nonane and their isomers ), cycloparaffins ( cyclopentane, cyclohexane, ethylcyclopentane, etc . ) and aromatic hydrocarbons ( benzene, toluene, xylene, etc . ).
2.
A theoretical prediction estimated this to be-800 to-950 for steranes,-900 to-950 for hopanes, and-700 to-950 for typical cycloparaffins between 0 �C to 100 �C . At the temperature of the oil window and gas window, the equilibrium fractionation between different group of organic molecules is relatively small, as compared with large primary signals.
