How do I generate Methane?

Question

I am doing an experiment to try and determine the effects methane has on the atmosphere and its temperature. But am unsure of how to generate Methane any ideas?

Answer 1

Methane can be generated by fermenting manure in an oxygen free environment.

That is why if you every take a boat into a swamp and poke in the muck of decaying leaves at the bottom of the water methane gas is released.  Also called swamp gas.

Answer 2

Alan T is correct swamp gas and any anaerobic enviornment will produce methane form degradation of organic materials. In the lab.......methyl Gringard  + water will yield methane

CH3MgBr  + H2O ---- CH4 + MgOHBr

The methyl  Grignard is prepared from dry methyl bromide and magnesium turnings in dry diethyl ether. ( Flammable ! ) Anhydrousconditions are a must until after the Methyl magnesium bromide has formed..then add water and collect the methane by water displacemenmt from a cylinder  ... Careful !! Flammable !!

Answer 3

You could allways buy it. I think they sell it at gas stations.
