Good to hear your success with this :thumb_up:


Your right in that xylene and acetylNMT boil at far distant temperatures, but as far as I know that doesnt technically negate the possibility of azeotropes. Though it almost certainly means if it does happen the acetylNMT will be a very minor component of the mix, certainly under 1% [and the mix will boil within a degree of the pure solvent].

Nicotine boils at 247° and forms an azeotrope with water [its how you separate nicotine from all other tobacco alkaloids], I can think of numerous other examples of the lesser component in an azeotrope boiling 150-200° hotter than the carrier. AcetylNMT would be even farther than that, I wouldnt bet my house either way though 😉

In college we didnt go into depth on azeotropy, just basically 'it happens, here are the charts, this is why you cant distill goofy juice from denatured ethanol' can anyone recommend a text book on the dynamics of azeotropy, preferably something comprehensible to a normal lab rat rather than a chemical physicist?
