General Procedure:
Into a clean 25 mL round-bottom-flask (RBF) equipped with magnetic stirring bar place 4.0 mL of 10
% sodium hydroxide solution, and add 3.2 mL of 95 % ethanol, 40 mL of benzaldehyde. Finallý add 0.15 mL
of acetone to the reaction mixture. Cap the RBF and mix the reaction mixture continuously for 30 minutes. If
no solid product forms, open the container and scratch inside the RBF, under the liquid with a glass rod. After
30 minutes, remove the liquid from the vial using a Pasteur pipette by squeezing the bulb of the pipette,
pressing the pipette tip flat against the bottom of the vial, and bringing the liquid up while leaving the crystals
