How do you get methanol from methane?
I am not aware of any direct way of producing methanol from methane. The only two ways I know that you can make methanol is by reacting carbon monoxide with hydrogen or by the pyrolysis of wood. Almost all the methanol made today is produced by the Syngas method. In it, methane is converted to carbon monoxide and hydrogen, which are then formed into methanol. Researchers are working on a catalyst to directly convert methane to methanol, which is done by inserting one oxygen atom into a methane molecule, between the carbon atom and a hydrogen atom. Their biggest problem right now is the most efficient catalysts work at temperatures high enough to ignite methanol.
Methanol. CH4 is Methane. OH is an alcohol (so you ad the "ol" ending). So you get: Methane + ol --> Methanol. It is a poisonous alcohol commonly synthesized from methane gas (natural gas), typically of petroleum origin, but also possible from natural "biogas". It is used in "racing fuel", biodiesel production, as well as a solvent.
Methane is part of a group of organic hydrocarbons called alkanes which have only one carbon atom per molecule CH4, whereas methanol belongs to the alcohol group with an OH, CH3OH. So although they are related in name with meth- only because they contain one Carbon atom in their structure they are two different molecules and have different properties.
Yes methanol has a far higher boiling point than methane. Methane is a gas at room temperature while methanol is a liquid. Alkanes such as butane have very low boiling points, while alcohols that have small R groups, have relatively high boiling points. The main reason for this phenomenon is than alcohols have Oxygen and Hydrogen in positions that make [Hydrogen Bonding http://en.wikipedia.org/wiki/Hydrogen_bond] possible.
Is there any possibility for coversion of CO2 and H2O produced from combustion in automobiles into CH4?
I am not aware of a process that can convert these compounds into methane. However I have read of an article where developement of a solar cell that generates electricity through some mechanism of reacting carbon dioxide and water to generate methanol. It may not be methane but methanol in of itself is also valuable as a fuel and to generate electricity through a byproduct is just astounding.
Generally speaking 'like dissolves like' so when you thinking if a molecule can dissolve in a particular solvent, you need to decide what type of bonding that solvent can exhibit and what bonding the molecule in question exhibits. So for example water can exhibit hydrogen bonding. This means for something to be able soluble in water, it too needs to be able to exhibit hydrogen bonding. Methane only contains hydrogen and carbon and thus, will…
Why methane mercaptan has a lower boiling point than methanol even though methyl mercaptan has a higher molecular weight?
Methanol is made by a method different from that used in the preparation of ethanol. The naphtha fraction from the distillation of crude petroleum, is used as a raw material for the manufacture of methanol. When naphtha is reacted with a high steam ratio, under pressure and at a high temperature, synthesis gas of low methane content is obtained. Most of the carbon from the naphtha is converted to carbon monoxide and carbon dioxide which…
