1.) Would recrystallization work if you more impurity than product and both were soluble in the recrystallization solvent at its boiling point and insoluble at room temperature? Why is it important to perform a hot gravity filtration of the impurities instead of a gravity filtration at a lower temperature? If all the physical characteristics of your isolated material matched that of ASA, except the melting point range was very broad and lower than the reported value, what could be the 2.) 3.) cause?
