cyclohexane

Hexahydrobenzene is a colorless pungent liquid. Insoluble in water, soluble in most organic solvents. Extremely flammable. It can be used as common solvent, standard material for chromatographic analysis and for organic synthesis. It can be used in resins, coatings, fats, paraffin oils, and can also be used to prepare cyclohexanol and cyclohexanone.

2. Appearance and properties: colorless liquid with pungent odor.

3, solubility: insoluble in water, soluble in ethanol, ether, benzene, acetone and other organic solvents.

4. State: it is a colorless liquid with gasoline odor, insoluble in water, miscible with ethanol, ether, acetone, benzene and other organic solvents. The solubility in methanol is 100 parts methanol, and 57 parts cyclohexane (25℃) can be dissolved.

5. Functions and USES

This product is used as solvent of rubber, coating, varnish, thinner of adhesive, oil extraction agent. Due to the low toxicity of this product, it is often used instead of benzene to degrease,

Remove grease and paint. This product is mainly used for making monomer adipic acid, adiphamide and caprolactam of nylon, and also used as raw material for making cyclohexanol and cyclohexanone.

Used as analytical reagents, such as solvents, for chromatographic analysis of standard substances. Also used in organic synthesis;

Complexometric titration of copper, iron, silicon, aluminum, calcium, magnesium, etc. Standard substances for chromatographic analysis;

4 as photoresist solvent;

5 for the extraction of essential oils;

Level 6 cyclohexane for cleaning agents, MOS is mainly used for discrete device, medium and large scale integrated circuit, BV - Ⅲ grade is mainly used in very large scale integrated circuit.
