The chloromethane is then dried by treatment with concentrated sulfuric acid, compressed, cooled, and stored. In the methane chlorination process, a molar excess of methane is mixed with chlorine, and the mixture is then fed to a reactor, which is operated at 400 °C and 200 kPa pressure (Holbrook 1992; Key et al.
How does chlorination of methane occur?
The organic product is chloromethane. One of the hydrogen atoms in the methane has been replaced by a chlorine atom, so this is a substitution reaction. However, the reaction does not stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.
What is the uses of chloromethane?
Chloromethane, or methyl chloride (74-87-3), is a naturally formed ubiquitous gas that is used primarily in the manufacture of silicones, but was formerly used as a refrigerant and anesthetic. It is metabolized to formaldehyde and formate, which is incorporated into the one-carbon pool and macromolecules.
How is methane prepared?
Methane is synthesized commercially by the distillation of bituminous coal and by heating a mixture of carbon and hydrogen. It can be produced in the laboratory by heating sodium acetate with sodium hydroxide and by the reaction of aluminum carbide (Al4C3) with water.
How is methane converted to methanol?
The two-step process produces liquid methanol by the steam reforming of methane to synthesis gas followed by the high pressure catalytic conversion of the synthesis gas to methanol. Partial oxidation route offers the advantage of directly converting methane to methanol in a single step reaction.
What is the by product during chlorination of methane?
In this step, one hydrogen atom of methane is replaced by the chlorine atom. Thus, it is a substitution reaction. The product formed is known as chloromethane.
Which product is obtained when chloromethane is reduced?
two chloromethane molecules react to form ethane.
Why is chloromethane not pure?
The formation of chloromethane from methane and chlorine is not pure because this is an example of substitution reaction in which H atom is replaced by Cl atom one by one which leads to several by products along with chloromethane. …
Does chloromethane dissolve in water?
Chloromethane can dissolve in water, and small amounts of chloromethane in air may go into surface waters or groundwater when it rains.
How much methane can kill you?
Asphyxiation becomes a risk when there are high concentrations of methane. This is because the methane displaces the oxygen. We need approximately 18% oxygen to breath, levels below 16% can be dangerous and levels below 10% can cause immediate loss of consciousness and inevitably death.
