Distillation of nitromethane from hobby fuel...

[gruns]

Now try burning the azeotrope of nitro and meoh

Ok a 50/50 mix of meoh and nitro burned the same color as the nitro that swim distilled did. The only difference was an occasional orange spark and how easily it ignited as compared to the distilled nitro. Good thinking gruns swim didnt even think of that...
So... 2 hours ago swim thought he had 99% nitro b/c of the nice blue flame but now swims not too sure   . Suggestions anyone?

After you distill then measure the density of the distillate to determine the ratio of nitromethane to methanol - nitromethane is much denser than methanol. The easiest way to do this is with a hydrometer - this is what the top fuel people use.
