Defat and reducing volume

Migrated topic.

So someone's pet fly decided to extract. The places weren't ideal, the temperature was only around 16C and did 1kg of mimosa in about 16L of water with 750g caustic soda. Bartoline low odour white spirit was used, overall about 800ml over a few pulls. Now this fly can't get a warm place for a while, but has this liquid which doesn't want to precipitate yet is clearly full of goodies.
He was thinking that this solvent will take ages to evaporate so was thinking of doing an alternative defat while reducing the volume.
Their plan was:
take the white spirit and mix it 50/50 with either filtered lemon juice or distilled vinegar.
mix it all together nicely, separate out and discard the white spirit. Then add enough caustic soda to basify it, warming it all up nicely and putting in hot white spirit just enough to dissolve it (should stop being cloudy?) and then freezing that.
Does anyone see any flaws here?
PS: the fly says that the tiny amount produced was very very clean.
 
You could salt, base and pull again, yes. But definitely do more than one vinegar pull to get all the alks out

Also that sounds like a lot of solvent being wasted. But if you cant warm the solvent up + fan to pre-evap, your option could be the best

Also remember you're gonna have to do more than one pull on that basified product. Ideally a few pulls, and small warm ones so you dont have to preevap
