Experiment 11: Synthesis of Aspirin pre-lab (4 pts) 1) (2 pts) Refer to the introduction on interpreting the ferric chloride test for phenols. Two students performed the aspirin synthesis experiment. Their melting point and ferric chloride test data are shown below. Based on the results, which student’s aspirin has the higher purity? Justify your choice using the melting point data and ferric chloride test results. Melting point range for pure aspirin = 136-140 °C. Melting point range (°C) Ferric chloride test Student A 132 – 142 purple Student B 135 – 139 clear / faint yellow 2) (2 pts) The reaction for the synthesis of aspirin is shown below: OH 0 0 НАРО, HC och HC OH он Acetic anhydride Salicylic acid d = 1.082 g/mL 0CH, MM = 138.12 g/mol MM = 102.09 g/mol Aspirin (acetyl salicylic acid) MM = 180.16 g/mol A student starts with 1.5 g of salicylic acid and 5.0 mL of acetic anhydride. She recovers 0.79 g! of aspirin (product). Determine the following… – theoretical yield -% yield [% yield = (actual yield /theoretical yield) x 100%] *Show your calculations!*
