The sample was transferred into a 125-mL Erlenmeyer flask. To the flask, 15 mL of ether and 15 mL of 5% NaOH were added. The flask was swirled until the material dissolves and then poured into the separatory funnel. The flask was washed with 10 mL of ether and poured into the separatory funnel. The separatory funnel contents were then swirled in the hood while making sure to vent. After mixing, the layers were allowed to separate. The aqueous layer was collected by opening the stopcock into a clean Erlenmeyer flask. The ether layer was extracted again with 10 mL of 5% NaOH and the aqueous layer was then added to the flask with the first aqueous extract. The ether layer was let to evaporate in the hood. The aqueous extract was added to the separatory funnel and the flask was rinsed with 20 mL of ether and 5 mL of water. The aqueous layer was then separated and
