What is 4-methylcyclohexane methanol used for?
That’s where 4-methylcyclohexane methanol, MCHM for short, comes in. MCHM is used in washing coal, helping separate the burnable fossil fuel from the unburnable rock and dirt and other impurities.
What is 4-methylcyclohexane?
4-METHYLCYCLOHEXENE. 4-Methyl-1-cyclohexene.
What is MCHM in water?
MCHM was the largest component of a mixture of chemicals that leaked from a corroded commercial storage tank upstream of the water supply for some 300,000 people. At the time of the spill, little was known about MCHM, an alicyclic alcohol used to process coal.
How do you make methylcyclohexane?
It can be also produced by hydrogenation of toluene: CH3C6H5 + 3 H2 → CH3C6H. Methylcyclohexane, as a component of a mixture, is usually dehydrogenated to toluene, which increases the octane rating of gasoline.
Is 4 Methylcyclohexene a liquid?
Appearance: clear, colorless liquid. Flash Point: -1 deg C.
What is crude MCHM?
Crude 4-methylcyclohexanemethanol (MCHM) is an industrial solvent used to clean coal. Approximately 10 000 gallons of a liquid mixture containing crude MCHM were accidently released into the Elk River in West Virginia in January 2014.
What is the chemical PPH?
Glycol Ether PPH, also known as Propylene Glycol Phenyl Ether, is a slow evaporating glycol ether. The substance is a clear, slightly yellow liquid and it’s odor is low and faint. It is very hydrophobic, while it’s molecular weight is heavier than other similar solvents.
Is 4 Methylcyclohexene soluble in water?

Is methylcyclohexane safe?
Unconsciousness and death may occur at higher exposures. * Prolonged or repeated skin contact can cause cracking and drying of exposed areas. * Methylcyclohexane may affect the liver and kidneys. * Methylcyclohexane is a FLAMMABLE LIQUID and a DANGEROUS FIRE HAZARD.
Is methylcyclohexane volatile?
Vapors heavier than air. Methylcyclohexane is a cycloalkane that is cyclohexane substituted by a single methyl group. It is a cycloalkane and a volatile organic compound.
What does 4-methylcyclohexane methanol smell like?
4-methylcyclohexane methanol (or 4-MCHM) is a chemical that is used in certain industries for purification of coal for metallurgical operations and blending gasoline 4-MCHM is a colorless liquid, which has a sweet smell, like licorice.
How is 4-methylcyclohexanemethanol used to clean coal?
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.
How is 4-methylcyclohexane methanol related to licorice?
4-MCHM is a colorless liquid, which has a sweet smell, like licorice. It is highly soluble in organic solvents but slightly soluble in water due to its oily consistency Ingestion or exposure to 4-MCHM can lead to 4-Methylcyclohexane Methanol Poisoning. This may be accidental or intentional
What is the solubility of 4-methylcyclohexanemethanol in water?
4-Methylcyclohexanemethanol. Like other 8-carbon alcohols, such as 1-octanol, this compound is only slightly soluble in water but highly soluble in many organic solvents. The solubility of 1-octanol in water is 2.3 grams per liter.
