[Cz-chemistry] Need help in obtaining a suitable drawing for [[Vacuum Distillation]]

[Richard Mayes]

The pdf http://www.chem.queensu.ca/courses/06/chem397/ManipAirSens.pdf shows
a set-up that achieves the same result of the Perkin Distillation Head.  I
embarrassingly must admit that I had to look up the drawing you cited even
though we do air sensitive distillations all the time in our lab (mainly
metal chlorides and alkyltin compounds).   When we do our air sensitive
distillations, we use a modified Vigreux column coupled to a standard
jacketed condensation tube and have nitrogen purges on everything while we
distill the solution into a Schlenk-type vessel with a stopcock.  Our other
method, in the case of high boilers, is to use a short-path distillation
head that we can hook up to a vacuum pump, similar to that found on the
ChemGlass website (part # CG-1237).  The other distillation head on the
ChemGlass website (CG-1233) will also assist in air sensitive
distillations.

If you are interested in what we use, I can get you a drawing of our setup
in a few days.
