I know someone that solely did an nitro reduction in 2 solvents. One was only methanol and the other was done in tap water. The reactants were the same in both cases. However, the amalgam run in only water produced a much stronger MeAm smell with the PH paper turning nearly 12 obove the vapors. The PH paper would only turn 8.5 - 9.0 on the methanol run. The MeAm smell was so much stronger on the water run that it seemed the condensate comming off had to be at least 1/2 the strength (by smell) of lab grade aqueous 40%. I was wondering just how, if possible, this could be measured by weight to determine MeAm content. Is there a proportional graph or some formula to determine, say, if it weighs 0.95 g/ml that its xx percent MeAm? This stuff seemed to be worth collecting.
