Highly Aromatic Petroleum Solvent Naphthas

“…Further, should occasion demand, the petroleum industry has the materials and processes for the separation and commercial production of a number of individual aromatics of any required degree of purity. PETROLEUM crudes are exceedingly complex mixtures, but much has been learned of their composition in recent years, Rossini and co-workers (5,10,11,18,27,28,29), Fenske et al (20,21), and others (8,6) have separated and identified over seventy hydrocarbons in the gas and gasoline boiling ranges. These include all the normal paraffins, a good number of the possible isoparaffins, the simple naphthenes, cyclopentane and cyclohexane, and several alkylated cyclopentanes and cyclohexanes.…”
