Purification Methods |
The solid may contain phthalimide and K2CO3 from hydrolysis. If too much hydrolysis has occurred (this can be checked by extraction with cold Me2CO in which the salt is insoluble, evaporate the Me2CO and weigh the residue), it would be better to prepare it afresh. If little hydrolysis has occurred, then recrystallise it from a large volume of EtOH, and wash the solid with a little Me2CO and dry it in a continuous vacuum to constant weight.
