Naphtha is a hydrocarbon mixture with CAS number 8030-30-6. It does not have a specific IUPAC name because it is a mixture of various compounds, and its molecular formula varies depending on the specific components. Under normal temperature and pressure conditions, naphtha is a colorless to light yellow liquid with a characteristic odor. It is modeled as a mixture, and its composition can vary depending on the refinery's processing methods and the quality specifications of the desired products. At the consumer level, naphtha is used in the following products: ① Solvents: used as a solvent in the manufacture of paints, varnishes, and coatings; ② Chemical feedstock: used to produce various organic chemicals, such as plastics, synthetic rubber, and fibers; ③ Fuel: in some cases, it can be used as a fuel after further processing. In industrial applications, naphtha is used to manufacture products for the following industries: ① Petrochemicals: as a raw material for producing plastics, synthetic fibers, rubber, adhesives, coatings, and other petrochemical products; ② Fuels: through catalytic reforming and other processing processes, naphtha can produce high-octane gasoline components; ③ Asphalt: naphtha can be used as a raw material in the production of asphalt.
