Industrial Grade N-hexane CAS Number: 110-54-31. Nature Specification: 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.Usage: 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.
