A generic term referring to a class of colorless, volatile, flammable liquid hydrocarbon mixtures. Naphtha is produced through fractionation of petroleum, natural gas, or coal tar and is one of the highest volume liquid fractions of crude oil.  Light naphtha (aka natural gasoline or straight run gasoline) generally ranges from C5-C7. Light naphtha is a major raw material for production of gasoline, petrochemicals (especially ethylene), and solvents. Chevron Phillips Chemical is also able to use light naphtha as a feedstock to its Aromax® process.
