In recrystallization, fluted filter paper is used instead of a regular cone because it minimizes its contact with the glass funnel. Why is this important?
When isolating a solid compound after recrystallization, which is the appropriate technique to use, vacuum filtration or gravity filtration?
Occasionally you will have solid impurities “trash” in your heated recrystallization solvent. How do you remove these impurities?
Is recrystallization a good method for purifying any product?
In which case you would used a mic solvent recrystallization? Explain, give an example
Why would a solvent with a very high boiling point be inappropriate for a recrystallization? Too much solvent would be lost to evaporation during the heating phase of the recrystallization Impurities and the compound to be recrystallized would dissolve equally well in this solvent A high boiling solvent would not dissolve the compound to be recrystallized It would be difficult to remove residual solvent from the purified crystals
Diethyl ether and methylene chloride are generally not suitable for use in recrystallization, but are frequently used as extraction solvents. Explain
