Dear All,

How can a mixture of Ethanol and Pyridine be efficiently and totally seperated from the same mix by fractional distillation, which practically yields a constant boiling point mixture of 75 deg Centigrade.
Can both chemical & physical methods be deployed simultaneously ? eg
Can the Pyridine be chemically reacted to form a compound having a much higher boiling point (say with dil HCL, to form Pyridine.HCL ?) or was the distillation temp too high, so that both compounds just distilled over ?
The fractionating column had steel helices and was long enough.
Any suggestions ? Thanks in advance.

Can you salt out the pyridine with HCl and then just filter out the solid to get the ethanol?

Thanks for your answer, which is EXACTLY what I thought, it confirms !
Employ a chemical reaction followed by a physical one... Thanks !!
Best regards,

I'm not positive that it would work, but it's worth a shot, I suppose.
