Add 0.5g of benzoin and 4mL of ethanol to a 25mL Erlenmeyer flask and was swirled until it was fully dissolved. 0.1g of Sodium borohydride was then added over a span of 5 minutes. The minutes was then swirled for another 20 minutes. After collected in the ice water bath, 5mL of water was added with 0.3mL 6M HCl. Then the solution was clenched. The product was then collected. The product was allowed to dry for 15 minutes. The crude yield was then determined and the MP was found. Also, 1-2mg of the crude product was put aside for TLC analysis. The crude solid was then recrystallized from the acetone. The crystals are left to dry overnight. The TLC analysis was completed. One of the plates consisted of starting material, the reaction product, and a co-spot of the starting material, and the reaction product. The second plate consisted of starting material, crude product, and co-spot of the starting material, and the crude product. After the TLC analysis was completed, the plates were inspected under UV light and then put into an iodine chamber for further analysis.
