Bees are told that the use of thicker Al is the way to go for safer, less exothermic reactions, that will not gobble up the Al too quick and therefore lead to a complete conversion of the ketone.
Yeh, swims runs a fair amount hotter, but its still managable, just not as subdued as methylman's and gonzo's pages say... as swim said if one uses ~10% more alu foil when using the thinner bbq plate things instead of raynolds wrap it makes it a bit better, swim used to have a fair amount of ketone left over until he realised this....
is the formation of methylamine from nitromethane slower also, now that thicker aluminium is used?
Maybe.... swim thinks there is a balance, to thin and the reaction is out of fuel before you get all the ketone in, and left with heaps unreacted as swim used to... to thick and it runs to bloody slow.... raynolds wrap is a good middle ground, but swim thinks if you had thick stuff and cut it and balled it into really small pieces it should even it out??
