메틸사이클로헥산 C화학적 특성, 용도, 생산

화학적 성질

Methylcyclohexane, an alkene, is a colorless liquid with a faint benzene-like odor. The odor threshold is 630 ppm (this is above the OEL).

물리적 성질

Clear colorless, very flammable liquid with a faint odor similar to benzene or cyclohexane. An odor threshold concentration of 150 ppb_v was reported by Nagata and Takeuchi (1990).

용도

Methylcyclohexane is used as a solvent and reagent in organic synthesis and polymer chemistry. It is a component of jet fuel and also used as correction fluid in certain consumer products. It acts as a starting material for toluene synthesis

용도

Methylcyclohexane is an environmentally friendly coating, mainly used as solvent for ink, rubber, paint, varnish, oil and grease extraction solvent, chromatographic analysis standard substance, also can be used in organic synthesis and analytical reagents.

생산 방법

Methylcyclohexane is separated by distillation from crude petroleum oils, and also produced by hydrogenation of toluene, reaction of benzene with methane, or acidic hydrocracking of polycyclic aromatics.

일반 설명

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.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

Saturated aliphatic hydrocarbons, such as Methylcyclohexane, 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.

위험도

Flammable, dangerous fire risk. Lowerexplosive limit 1.2% in air. Upper respiratory tractirritant, central nervous system impairment, liverand kidney damage.

건강위험

Harmful if inhaled or swallowed. Vapor or mist is irritating to the eyes, mucous membrane and upper respiratory tract and skin. Narcotic effects and dermititis.

화재위험

Special Hazards of Combustion Products: Vapor may travel considerable distance to a source of ignition and flashback containing explosion may occur during fire conditions. Forms explosive mixtures in air.

Safety Profile

Moderately toxic by ingestion. Mildly toxic by inhalation and skin contact. This material does not cause irritation to the eyes and nose, and, even at the level of 500 ppm, exhbits only a very faint odor. Therefore, it cannot be said to have any warning properties. It is believed to be about three times as toxic as hexane, and has caused death by tetanic spasm in animals. In sublethal concentrations, it causes narcosis and anesthesia. Dangerous fire hazard and moderate explosion hazard when exposed to heat, flame, or oxidzers. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes.

잠재적 노출

Methylcyclohexane is used as a solvent for cellulose derivatives particularly with other solvents; and as an organic intermediate in organic synthesis. A component of jet fuel.

환경귀착

Biological. May be oxidized by microbes to 4-methylcyclohexanol, which may oxidize to give 4-methylcycloheptanone (Dugan, 1972).
Photolytic. Based on a photooxidation rate constant 1.04 x 10^-11 cm³/molecule?sec for the reaction of cyclohexane and OH radicals in the atmosphere at 298 K, the estimated lifetime of methylcyclohexane is 13 h (Altshuller, 1991).
Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. Methycyclohexane will not hydrolyze in water because it does not contain a hydrolyzable functional group.
Complete combustion in air yields carbon dioxide and water. Incomplete combustion also yields carbon monoxide.

Purification Methods

Passage through a column of activated silica gel gives material transparent down to 220nm. It can also be purified by passage through a column of activated basic alumina, or by azeotropic distillation with MeOH, followed by washing out the MeOH with H2O, drying and distilling. Methylcyclohexane can be dried with CaSO4, CaH2 or sodium. It has also been purified by shaking with a mixture of conc H2SO4 and HNO3 in the cold, washing with H2O, drying with CaSO4 and fractionally distilling it from potassium. Percolation through a Celite column impregnated with 2,4-dinitrophenylhydrazine (DNPH), phosphoric acid and H2O (prepared by grinding 0.5g DNPH with 6mL 85% H3PO4, then mixing with 4mL of distilled H2O and 10g of Celite) removes carbonyl-containing impurities. [Cowan et al. J Chem Soc 1865 1939, Beilstein 5 III 65, 5 IV 94.]

비 호환성

Vapor may form explosive mixture with air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Attacks some plastics, rubber and coatings

폐기물 처리

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
