Production and use
Methylcyclohexane can be also produced by hydrogenation of toluene:
CH3C6H5 + 3 H2 → CH3C6H11
Methylcyclohexane, as a component of a mixture, is usually dehydrogenated to toluene, which increases the octane rating of gasoline.
Methylcyclohexane is also one of a host substances in jet fuel surrogate blends, e.g., for Jet A fuel.
Solvent
Methylcyclohexane is used as an organic solvent, with properties similar to related saturated hydrocarbons such as heptane.
Methylcyclohexane is also a solvent in many types of correction fluids.
Structure
Methylcyclohexane is a monosubstituted cyclohexane because it has one branching via the attachment of one methyl group on one carbon of the cyclohexane ring.
Like all cyclohexanes, it can interconvert rapidly between two chair conformers.
The lowest energy form of this monosubstituted Methylcyclohexane occurs when the methyl group occupies an equatorial rather than an axial position.
This equilibrium is embodied in the concept of A value.
In the axial position, the methyl group experiences steric crowding (steric strain) because of the presence of axial hydrogen atoms on the same side of the ring (known as the 1,3-diaxial interactions).
There are two such interactions, with each pairwise methyl/hydrogen combination contributing approximately 7.61 kJ/mol of strain energy.
The equatorial conformation experiences no such interaction, and so it is the energetically favored conformation.
Methylcyclohexane appears as a clear colorless liquid with a petroleum-like odor.
Flash point 25°F.
Less dense than water and insoluble in water.
Vapors heavier than air.
Methylcyclohexane is a cycloalkane that is cyclohexane substituted by a single methyl group.
Methylcyclohexane has a role as an aprotic solvent, a plant metabolite and a human metabolite.
Methylcyclohexane is a cycloalkane and a volatile organic compound.
Methylcyclohexane derives from a hydride of a cyclohexane.
Methylcyclohexane is a natural product found in Acca sellowiana, Carica papaya, and other organisms with data available.
Used commercially as a solvent for cellulose derivatives particularly with othersolvents, and as an organic intermediate in organic synthesis.
Methylcyclohexane is one of the components found in jet fuel.
