Description
Also known as Naptha. Naptha is a general term applied to refined, partly refined, or unrefined petroleum products and liquid products of natural gas, not less than 10% of which distill below 175°C (347 °F) and not less than 95% of which distill below 240 °C (464°C)when subjected to distillation in accordance with the Standard Method of Test for Distillation of Gasoline, Naphtha,Kerosene,and Similar Petroleum Products(ASTMD86). Used as a source, by various cracking processes, of gasoline, special naphthas, petroleum chemicals, especially ethylene. Cracking for ethylene also produces propylene, butadiene, pyrolysis gasoline,and fuel oil, source of synthetic natural gas.

Physical properties
Petroleum ether is a colorless transparent liquid, slightly odor, low polarity. Petroleum ether is a mixture of various small molecule ethers after petroleum cracking. According to the boiling point, it can be divided into 30-60℃?and 60-90℃.It is insoluble in water and can be miscible with acetone, ether, ethyl acetate, benzene, chloroform and higher alcohols above methanol. It can dissolve synthetic resins such as coumarone resin and triglyceride rosinate. Partially dissolves rosin, pitch, frankincense and aromatic resins. Does not dissolve shellac and alkaloids. Except for castor oil, most liquid fats are soluble, and solid fats are slightly soluble. The fatty acid is soluble, but the hydroxy acid is hard to dissolve, so petroleum ether can be used to separate the hydroxy acid mixed in the fatty acid. Raw rubber and vulcanized rubber swell significantly in petroleum ether. Chlorinated rubber, nitrocellulose, cellulose acetate, benzyl cellulose, etc. are insoluble in petroleum ether.
