Methylcyclohexane

Methylcyclohexane is an organic compound with the chemical formula C₇H₁₄. It is a colourless liquid with a mild, sweet odour, and is classified as a hydrocarbon. Methylcyclohexane is used in a variety of applications, including as a solvent in chemical industries, in the production of rubber, and as a component in the manufacture of fuels.

Structure and Properties

Methylcyclohexane is a cycloalkane and consists of a six-membered carbon ring with one methyl group attached. The carbon atoms in the ring are sp3 hybridized, meaning they form four bonds in a tetrahedral geometry. The molecular structure of methylcyclohexane allows for two different conformations: the axial and equatorial conformations.

The physical properties of methylcyclohexane include a boiling point of 101 °C (214 °F) and a melting point of -126.3 °C (-195.3 °F). It is less dense than water and is insoluble in water but soluble in ethanol and ether.

Production and Uses

Methylcyclohexane is produced industrially by the hydrogenation of toluene, a process that involves the addition of hydrogen to the toluene molecule under high pressure and temperature.

In the chemical industry, methylcyclohexane is used as a solvent due to its ability to dissolve a wide range of substances. It is also used in the production of rubber and as a component in the manufacture of fuels.

Safety and Health Effects

Exposure to methylcyclohexane can cause irritation to the eyes, skin, and respiratory tract. It can also cause central nervous system depression and damage to the liver and kidneys. Therefore, it is important to handle methylcyclohexane with care and use appropriate personal protective equipment.
