Can you add a vigreux column to a rotovap set up and do a fractionate distillation?A rotovap looks like a regular distillation set up except the
evaporating flask is rotate so i guess it could be possible but i heard you cant use it to purify a liquid.

If you very accurately controlled the temp. of the water bath you could distill something.
But where would you put the vigreux column?Dariusrussell - 19-10-2013 at 14:17
I think you will run into significant issues attatching a decently sized vigreux as it would snap.
Would this be done under vacuum like a usual rotovap?jack33 - 19-10-2013 at 15:26
I would put it above the evaporating flask but not on the same side(i would rest the receiving flask on a stand) or vertically below the condenser.
I would use a vacuum and a thermometer too.kristofvagyok - 19-10-2013 at 15:27

No, no, no and no. Rotavap is for removing volatile solvents, if you would like to do a distillation, than do it properly.Dariusrussell - 19-10-2013 at 16:50
Alternatively... If you have a rotovap and you don't want to get more glassware and it can be put on a steep angle you could make it work without the
roto, and evap; using it just as a distillation setup(1). But if you have a rotovap you should be able to get the rest of a vacuum fractionating
setup.
(1) I highly don't recommend it though.
