Naphtha, any of various volatile, highly flammable liquid hydrocarbon mixtures used chiefly as solvents and diluents and as raw materials for conversion to gasoline. Naphtha was the name originally applied to the more volatile kinds of petroleum issuing from the ground in the Baku district of Azerbaijan and Iran Naphtha definition, a colorless, volatile petroleum distillate, usually an intermediate product between gasoline and benzine, used as a solvent, fuel, etc. See more. DICTIONARY.CO Naphtha is an important resource used to produce petrochemical products. Historically, petrochemical companies have been keen to the variations of naphtha prices as it has had great effects on their profits. Naphtha price is closely aligned with crude oil price. In particular, more directly, supply and demand of naphtha affect its price fluctuations Naphtha chemicals can be harmful to humans in various ways. If a human's skin or eye comes into contact with naphtha, the area can become irritated and begin to swell and feel painful. Flush skin and eyes immediately after contact. Ingesting the substance causes nausea, lung damage, respiratory failure and death in some cases

Naphtha (CAS No.: 8032-32-4, 8030-30-6, 8002-05-9; aka petroleum ether, white spirit (though in the UK white spirit is something completely different), Ligroin; VM&P Naphtha (CAS No. 64742-89-8); Varnish Makers and Painter's Naphtha [1]; Benzin; Petroleum Naphtha, Naphtha ASTM, Petroleum Spirits, Shellite, Ronsonol, Energine; not to be confused with Naphthalene) is a group of various liquid. Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil with CAS-no 64742-48-9. It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or petrol)

Naphtha (/ [invalid input: 'icon'] ˈ n æ f θ ə / or / ˈ n æ p θ ə /) normally refers to a number of flammable liquid mixtures of hydrocarbons, i.e., a component of natural gas condensate or a distillation product from petroleum, coal tar or peat boiling in a certain range and containing certain hydrocarbons. It is a broad term covering. Naphtha is the technical term for petroleum fractions that are rich in cycloalkanes (ring-shaped, saturated hydrocarbons). This colorless (with kerosene smell) or red-brown liquid (with an aromatics odor) intermediate product lies between the light gases of crude oil and the heavier, liquid kerosene and is insoluble in water Naphtha is catalytically reformed to produce a high-octane gasoline blending component. Catalytic reforming is also a very important refinery process for another reason: the reformer is a significant source of the hydrogen required by various critical processes across the refinery and is often in short supply Naphtha is a flammable liquid hydrocarbon mixture. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions naphtha may also be crude oil or refined products such as kerosen Naphthalene is a white, volatile, solid polycyclic hydrocarbon with a strong mothball odor. Naphthalene is obtained from either coal tar or petroleum distillation and is primarily used to manufacture phthalic anhydride, but is also used in moth repellents.Exposure to naphthalene is associated with hemolytic anemia, damage to the liver and neurological system, cataracts and retinal hemorrhage
