purpose | This product can dissolve resin, wax, asphalt, rubber and drying oil, and is used as an organic solvent. This product is also a reference substance for gas chromatography. The product is a Class I flammable liquid. used as standard substance for chromatographic analysis |
production method | Methylcyclopentane is mainly present in industrial hexane, and the content is about 5%. However, because its boiling point is close to the boiling point of n-hexane (68.74 ℃), it is difficult to completely separate it by General distillation method. Therefore, the azeotropic distillation method with methanol is adopted, methylcyclopentane with a purity of more than 99% can be obtained. |
