-
uses
methane
-
-
preparation of - ethyne , methanal , methanol
ethane
prepation - ethene, ethanol, ethanal

-
substitution can be seprated by fractional distillation because of appreciable differences in their respective b.p
Catalytic oxidation
when a mixture of methane and oxygen in ratio 9:1 by volume is compressed to about 120 atm pressure methyl alcohol is formed
when a mixture of methane and oxygen is passed through heated molydenum oxide the mixture is oxidised to methanal
