How would you seperate p-nitro benzaldehyde and p-nitrobenzyl alcohol in ethanol from each other without using column chromatography?

Question

aaronq · Answer

You could probably exploit their chemical differences to change the solubility of one of them in the solvent.

aaronq · Answer

I looked up their BPs and they vary by like >100 degrees, you could probably distill one from the other, unless they form azeotropes with ethanol..which they might.

anonymous · Answer

Well if you were to do distillation, you could just boil ethanol off because it has a bp of 78 c degrees, and then do distillation of the the aldehyde and alcohol?

anonymous · Answer

boil via steam bath

aaronq · Answer

hm, that sounds fine in theory but you might get some weird waxy mixture once you boil off the ethanol. you'd have to try it to see if it's possible.

Do you have access to scholarly journals?

aaronq · Answer

there's probably an easier way. have you done any research into it?

photon336 · Answer

distillation would be ideal if their boiling point difference is larger than 30 degrees.
