Product Details

Cyclohexane CAS# 110-82-7

Cyclohexane is a normal alicyclic hydrocarbon, which is a ring shape composed of six carbon atoms, every of which is linked to two hydrogen atoms. It has two most important conformations: chair and boat, of which the chair conformation is the most stable. It is a colorless liquid with a pungent smell at room temperature and pressure. It is insoluble in water, however miscible with most natural solvents such as ethanol, ether, benzene, and acetone. This solubility attribute approves it to be properly blended with many natural solutes when used as a solvent in natural chemistry experiments and industrial production.
