so an a/b has been done, you have your pureified salt in your non-polar. would it not be reasonable to basify and filter the needed substance, rather than evaporating, saving the solvent for future use or have i just been awake for too long?
thanks

What are you doing? You need more infomation than this.

say extractiing pfed for example. in the final stage you have pure pfed dissolved in polor solvent (meant to say polar rather than non-polar originally). rather than evap. it off, would it not be faster to basify and filter? everywhere i read it say to evap.
thank you :)

If you find evaporating so hard why not just gas the non-polar instead of extracting into acidic solvent? HCl is made very easily with hydrochloric acid and sulfuric acid. Look it up on ../rhodium.

It is on Rhodium's in detail. Basicly, you drip hydrochloric acid into sulfuric acid. The sulphuric dehydrates the HCl, giving you HCl gas. Add an inline dryer and suck back trap and there you have it.
Please be careful gassing. As simple as it sounds, one mistake can flood your lab with HCl. I would guess at least 1/2 the bees who gas have some gassing disaster story (myself included). If it is possible, gas outdoors or under a fume hood.
