I'm assuming you would do an extraction to do this but I honestly have no idea. I thought maybe you could dissolve the adipic acid in ethanol or water (or a mixture of the 2) and do a simple distillation but I'm really lost. Any advice is appreciated!

what do acids react with that alcohols don't?

There are several ways to do this based on solubility. There are also several ways to proceed based on Bronsted Lowry A/B Chem. I like your distillation idea, but watch for azeotropes. If you don't understand basic azeotropes, read a smidgen on it, and it will help you grasp distillation (all kinds) with a much more scientific understanding. I also like discodermolides idea…….thats the beautiful part about this subject!!!!!! It is so open for discussion and thinking!!!!!

CHECK THEIR BOILING POINTS!!!!!!!!!!! Adipic acid boils waaaaaay higher i would imagine. Cyclohexanol is around 160-165 C if I remember correctly. Check Adipic acid ;). There is your answer.

What's wrong with an extractive separation? Why muck around with distillation apparatus, probably even with vacuum.
Extraction is the way to go.

All preference my man. Although, you are CORRECT in your suggestion of lab ware setup. I looked up the difference, and it is VERY obvious which comes over at a lower temp. (cyclohexanol). Get a nice mixture with LOTS of boiling stones going, and start increasing to around 160 C slowly. Cyclohexanol comes over in good quantity, as long as that 160 is MAINTAINED.

scorching of other product not likely because the BP is WELL over 200.
