Dear comrades!
I have a purely hypothetical :) question for you. The question of uttermost importance and urgency. It already has been asked a year ago (Post 241813 (https://www.thevespiary.org/talk/index.php?topic=8833.msg24181300#msg24181300)
(placebo: "GBL - BDO seperation?", Methods Discourse)), but 'nuffin come of it', alas :( .
So. Suppose, one had a mixture containing of, say, 90+% GBL and 10-% 1,4-butanediol.
How would one go about thorough cleaning of GBL w/out fractional distilling? (suppose, one has no means of fractional distillation ::) )
Thus far i have two thoughts:
1) Dump in some baking soda (as in Post 283023 (https://www.thevespiary.org/talk/index.php?topic=9661.msg28302300#msg28302300)
(Chromic: "GHB synthesis - a must read", Methods Discourse)), convert to Na-GHB. Then extract the remaining butanediol with some NP solvent.
The questions:
- what solvent will extract BDO better than water? Will any?
- can steam-distillation bee substituted for extraction, i.e. - DOES BDO steam-distill?
2) Another possibility - that is, in case BDO is REALLY hydrophyllic is to dilute the mixtr w/water and salt GBL out.
The questions are:
- how efficient this could bee? (i.e., how much GBL is going to bee wasted)
- will this work at all?
PLEASE, bees, help SWIM in this hypothetical situation if you can, and as soon as you can! :)
Thanx in advance,
Antoncho
