Methylcyclohexane, as a component of a mixture, is usually dehydrogenated to toluene, which increases the octane rating of gasoline. [4] The conversion of methylcyclohexane to toluene is a classic aromatization reaction. This platinum (Pt)-catalyzed process is practiced on scale in the production of gasoline from petroleum. [10]
4-Methylcyclohexene is an organic compound consisting of cyclohexene with a methyl group substituent attached to carbon most distant from the alkene group. Two other structural isomers are known: 1-methylcyclohexene and 3-methylcyclohexene.
It has been patented for use in air fresheners. [8]U.S. Patent 4915825 describes a froth flotation process for cleaning coal where a mixture of 95% MCHM, 4% water, and 0.1% 4-methylcyclohexanemethanol monoether (such as 4-(methoxymethyl)cyclohexanemethanol) is used as a frothing agent, and finely divided coal particles adhere to air bubbles induced into the agent which rise to the surface.
This report does not include the findings and information released by the US Chemical Hazard and Safety Board, US National Toxicology Program, and other academic studies. Information disclosed as part of these studies indicated more than 100 mg/L of 4-MCHM was present in the Elk River, levels greater than 3.773 ppm 4-MCHM were present in the ...
Vapor pressure at 40°C of toluene is 7880 Pa and methylcyclohexane is 10900 Pa while DBT is 0.07 Pa and perhydro-dibenzyltoluene (H18-DBT) is 0.04 Pa. [17] This substance is currently being used as a heat transfer oil, for example, under the trade name Marlotherm SH. [18] Temperatures of approx. 300°C are necessary for dehydrogenation.
Aliphatic compounds can be saturated, joined by single bonds (), or unsaturated, with double bonds or triple bonds ().If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound.
