Extraction technique
« on: April 03, 2021, 10:16:46 PM »
Is it possible to use acid-base extraction to extract 1,12-dibromododecane from a mixture of 1,12-dibromododecane and 12-bromododacan-1-ol?

Please read the forum rules.

When (and how) does the acid-base extraction works?

I was thinking about using an aqueous NaOH solution. So in a separatory funnel, combine the mixture of bromoalcohol with 1,12-dibromododacane in hexane, then add NaOH and mix it. Would this deprotonate the OH and make it move to the aqueous layer?

Have you checked the pKa valeus for alcohols compared to water?
If you where able to deprotonate the alcohol do you see any risc of side-reactions?
