What are disadvantages of using sublimation vs. recrystallization as a method of purification? I can only think that a small sample can be sublimed while a bigger sample size can be recrystallized. Are there more?
The most notable difference is that sublimation requires a volatile solid, whereas most solid can be recrystallized from a solvent system that is not too exotic.
Recrystallizations tend to recover more pure product.
In regards to green chemistry, sublimations are preferred as they generate no solvent waste.
