a) Succinimide is an organic compound used in many syntheses as a building block and is related to a class of drugs known as anticonvulsants. Given the following solubility of succinimide in water and methanol, which would be a better solvent for recrystallizing succinimide? Solubility data: 1 gram of succinimide is soluble in 5 mL of cold water, 3 mL of water at room temperature and 0.7 mL of boiling water. 1 gram of succinimide is soluble in 30 mL of cold methanol, 24 mL of room temperature methanol and 5 mL of hot methanol. Show calculations. b) A researcher wanted to purify 0.4 grams of crude succinimide via recrystallization using only 2 mL of solvent. Decide the best solvent to use (water or methanol) to show the maximum % recovery of the researcher. The best solvent chosen here, may differ from the one chosen in part a.

Question
a) Succinimide is an organic compound used in many
syntheses as a building block and is related to a class of drugs known as
anticonvulsants. Given the following solubility of succinimide in water and
methanol, which would be a better solvent for recrystallizing succinimide?
Solubility data: 1 gram of succinimide is soluble in 5 mL of cold water, 3 mL of
water at room temperature and 0.7 mL of boiling water. 1 gram of succinimide is
soluble in 30 mL of cold methanol, 24 mL of room temperature methanol and 5
mL of hot methanol. Show calculations.
b) A researcher wanted to purify 0.4 grams of crude succinimide via
recrystallization using only 2 mL of solvent. Decide the best solvent to use (water or methanol) to show the maximum % recovery of the researcher. The best solvent chosen here, may differ from the one chosen in part a.
