                                                  N-hexane

CAS Number: 110-54-3

1. Nature: Colorless, volatile liquid. Freezing Point -93.5 ° C, the boiling point 68.95 ° C, the melting point -95 ° C, the relative density of 0.6603 (20 / 4 ° C), refractive index of 1.37506, the flash point (a cup) -20 ° C, spontaneous combustion, 260 ° C, the critical temperature of 234.2 ° C, critical pressure 3.00MPa. Difficult to dissolve in water, soluble in ethanol, soluble in ether and chloroform, ketones, and other organic solvents.

2. Preparation: N-hexane in straight-run gasoline, platinum and restructuring of pumping more than oil or natural gas in the moist content of 1% to 15%. At present industrial production, mainly from platinum reforming unit of the raffinate oil (including hexane 11% -13%) in the separation. I will be pumping oil distillation separation, except for light component and reorganization, with hexane in the 60-80 percent of the distillate. A continuous distillation towers, and then the 0501 catalyst hydrogenation, to remove non-saturated hydrocarbons such as benzene, hexane in the qualified. The United States has also used adsorption separation prepared by n-hexane.

3. Purposes: The major use of N-hexane is to extract vegetable oils from crops due to its narrow distillation range and selective power. Its wide usages are in the rubber industry as a base for rubber cement and in tyre manufacture and in contact adhesives, paints and inks, where fast drying and ability to suspend are required. Application is also found in the manufacture of sbr rubber where hexane is used as a medium in the polymerization process.
