Petroleum ethers is a colorless transparent liquid, with the smell of kerosenes. It's mainly a mixture of pentanes and hexanes. Insoluble in water, soluble in anhydrous ethanol, benzene, chloroforms, oil and other organic solvents. Flammable and explosive, can react strongly with oxidizing agents. Mainly used as solvent and grease treatment. It is usually obtained from platinum reforming residual oil or straight run gasolines by fractionation, hydrogenation or other methods.

1. solvent -naphtha by boiling point range is divided into 120~160ºC, 120~180ºC, 140~200ºC three. It is used as a solvent for coatings made of coal-tar pitch, stearic acid pitch, petroleum pitch, etc. The high boiling point components are used as diluents for cellulose esters and synthetic resins, while the others are used as solvents for the manufacture of dye intermediates. Adding petroleum solvent to -naphtha can increase the solubility.
2. Used as chemical fertilizer, ethylene production and catalytic reforming raw material, can also be used in the production of solvent oil or as a blending component of -gasoline products.
