Name: cyclohexane Alias: Six hydrogenation of benzene nature: colorless liquid with a pungent odor. Solubility: insoluble in water, insoluble in most organic solvents. Status: for gasoline odor colorless mobile liquid, insoluble in water, miscible with many organic solvents such as ethanol, the solubility in methanol of 100 parts of methanol and 57 parts of cyclohexane-soluble (25 ℃). Used as solvent, and the standard substance used for chromatographic analysis of organic synthesis, may be resins, paints, fats, paraffin oils applied, may also be prepared cyclohexanol and cyclohexanone and the like organic compounds. Melting point (℃) 6.5 Relative density (water = 1) 0.78 boiling point (℃) 80.7 Flash point (℃) -16.5 refractive index of 1.42662 Relative vapor density (air = 1) 2.90 Uses 1, the materials used for rubber, paints, varnishes solvents, diluents adhesives, grease extraction agent. Due to toxicity of this product, so often used in place of benzene de-grease, de-grease and paint stripping. This product is mainly used in the manufacture of nylon monomers adipic acid, hexamethylene diamine and caprolactam, also used in the manufacture of cyclohexanol, cyclohexanone materials; 2, used as analytical reagents, such as solvent, chromatography analysis standard material. Also used in organic synthesis; 3, complexometric titration of copper, iron, silicon, aluminum, calcium, magnesium and the like. Chromatographic analysis standards; 4, used as a photoresist solvent; 5, the extraction of essential oils used; 6, cyclohexane as cleaning degreaser, MOS grade is mainly used for discrete devices, in LSI, BV- Ⅲ grade is mainly used for VLSI.
