Naphtha - Wikipedia
WebNaphtha (/ ˈ n æ p θ ə / or / ˈ n æ f θ ə /) is a flammable liquid hydrocarbon mixture. Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates , petroleum distillates , and the fractional distillation of coal tar and peat .

PETROLEUM NAPHTHA, [SOLVENT] | CAMEO Chemicals | NOAA
WebA clear colorless to dark brownish colored liquid with an aromatic odor. Less dense (6.1-6.3 lb/gal) than water and insoluble in water. Hence floats on water. Vapors heavier than air. Used in cleaning preparations, as a solvent, and as a raw material for making various chemicals. Flash point above 100°F.

WebNaphtha reforming. The most widespread process for rearranging hydrocarbon molecules is naphtha reforming. The initial process, thermal reforming, was developed in the late 1920s. Thermal reforming employed temperatures of 510–565 °C (950–1,050 °F) at moderate pressures—about 40 bars (4 MPa), or 600 psi—to obtain gasolines (petrols ...
