I use quite a bit of methylated spirits to clean electronic PCBs as part
of a cottage business I run. The solvent becomes laden with dissolved
rosin flux & has to be discarded so I've been thinking about distilling
it for reuse. It's costing me 3 or 4 dollars per litre.


I was toying with the idea of electrically heating an old pressure
cooker vented through either a copper coil or an old refrigerator heat
exchanger. I'm not sure if draping wet cloth on the heat exchanger would
be sufficient cooling.

I think the BP of the methylated spirits is ~ 82 Celsius (180F).
Has anyone any experience doing this sort of thing (moonshine perhaps?)

Will it be worth the effort?

A mate makes his own whiskey, He uses a reflux still which I doubt
you'd need and he says that trying to hold the correct temperature
without using some sort of automatic controller is a bit difficult but
doable.

(His current still is electric fired and all automated controls)
