General Description
Clear colorless liquids with a petroleum-like odor. Flash point between 51-61°F. Less dense than water and insoluble in water. Vapors heavier than air.
Reactivity Profile
Saturated aliphatic hydrocarbons, such as DIMETHYLCYCLOHEXANE(589-90-2), may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
Air & Water Reactions
Highly flammable. Insoluble in water.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Chemical Properties
clear colorless liquid
Uses
1,4-Dimethylcyclohexane (mixture of cis and trans) has been used to study the absorption of ultrasonic waves that can be measured by a reverberation technique.
Uses
Dialkylcyclohexane is used as a solvent. Dimethyl- and
diethylcyclohexane are used in catalytic reforming to produce
C8 aromatic compounds.
Definition
ChEBI: 1,4-dimethylcyclohexane is a cycloalkane that is cyclohexane substituted by a methyl group at positions 1 and 4. It has a role as a human metabolite and a plant metabolite. It derives from a hydride of a cyclohexane.
Purification Methods
Free it from olefins by shaking with conc H2SO4, washing with water, drying and fractionally distilling it. [Haggis & Owen J Chem Soc 411 1953, Beilstein 5 III 102, 5 IV 122.]
