Calculate the percent recovery from recrystallization. Diels-Alder Reaction Data: Mass of anthracene: 0.503g Mass of maleinanhydride: 0.251 g Mass of filter paper: 0.681 g Mass of filter paper and crude product: 1.192 g Mp of crude product: 250-262 C Mass of watch glass: 47.220g Mass of watch glass + recrystallized product: 47.694 g Mp of recrystallized product: 260-262
Calculate the percent recovery from recrystallization.
Diels-Alder Reaction Data:
Mass of anthracene: 0.503g
Mass of maleinanhydride: 0.251 g
Mass of filter paper: 0.681 g
Mass of filter paper and crude product: 1.192 g
Mp of crude product: 250-262 C
Mass of watch glass: 47.220g
Mass of watch glass + recrystallized product: 47.694 g
Mp of recrystallized product: 260-262 C
Given:-
Mass of filter paper=0.681g
Mass of filter paper + crude product=1.192g
Therefore mass of crude product=(1.192-0.681)g=0.511g
Also given:-
Mass of watch glass: 47.220g
Mass of watch glass + recrystallized product: 47.694 g
Therefore mass of recrystallised product= (47.694-47.220)g=0.474g
