When his supervisor asked University of Kent graduate student Andryj Borys to recrystallize 50 g of crude product made by undergraduates in the lab, Borys jumped at the chance. “I’m not going to decline the opportunity to work with a 2.5 L Buchner flask!” he says. The product shown was formed by reacting mesitylamine and glyoxal to yield bis-imine. To form the feathery yellow crystals, Borys dissolved the crude product in boiling ethanol and allowed the solution to cool slowly and undisturbed.
