Inject a 5 µL sample of EtOAc from the Simple Distillation. Determine the actual % recovery of the purified EtOAc based on the % composition observed from the gas chromatogram. 2. Inject a 5 µL sample of Fraction 1 from the Fractional Distillation. Determine the actual % recovery of the purified EtOAc

observed to be around 87 to 89 degrees Celsius. It ranged from about 77 degrees in fraction 1 to about 89 degrees in the fraction 10. Next‚ the toluene stayed relatively the same temperature throughout the first 6 fractions at around 69 degrees and then drastically shot up to 100 degrees by the end of fraction 10. This is due to hexane having a lower boiling point and being able to steadily increase through each fraction evenly as temperature rises while the toluene‚ because of its higher boiling component
