Molecular Formula Molecular Weight 99 (approx) Boiling Point 86-460F Freezing Point -99F Solubility Insoluble Vapor Pressure 40 mmHg (approx) Ionization Potential ? The virgin heavy naphtha is usually processed in a catalytic reformer, because the light naphtha has molecules with six or fewer carbon atomswhich, when reformed, tend to crack into butane and lower molecular weight hydrocarbons that are not useful as high-octane gasoline blending components. At levels of 1100 ppm, 10% of the lower explosive limit, petroleum naphtha is immediately dangerous to life and health. Naphtha (often referred to as naft in the older literature) is a generic term applied to refined, partly refined, or an unrefined low-to-medium boiling petroleum distillate fraction. Less dense than water and insoluble in water. Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil[1][2][3] with CAS-no 64742-48-9. 4. The difference between molecular weight of naphtha from Eq (1) and (3) is 0.2 %. Specialty naphtha comes in many varieties and each are referred to by separate names such as petroleum ether, petroleum spirits, mineral spirits, paraffin, benzine, hexane, ligroin, white oil or white gas, painters naphtha, refined solvent naphtha and Varnish makers' & painters' naphtha (VM&P). The chemical formula for water is H2O. Naphtha is known to be carcinogenic and cause respiratory and brain damage if too much is inhaled. (2) and (4) are used to calculate the molecular weight for a number of specific gravities and boiling points and the results, given with C and F, are shown in the figures below, See also Average boiling point from gravity and molecular weight and Molecular Weight - Gases and VaporsExample 1: Molecular weight of naphthaCalculate the molecular weight of a naphtha with specific gravtity, S = 0.763 and a MeABP of 292F.
