The Attempt at a Solution



Separate ephedrine by either simple distillation or rotary evaporator? It said to suggest an organic solvent, which I would assume as Ch2Cl2?
I'm thinking of these two as possible methods because it's similar to separation from caffeine. Any thoughts? This is a post-lab question btw.
