Experiment 7
The Separation of Three Organic Compounds by Acid-Base Reactions and Liquid-Liquid Extractions
Abstract:
The purpose of the experiment was to isolate the three mixtures 9-fluorenone , benzoic acid and benzocaine by the liquid-liquid extraction method and the acid-base reaction technique. Using the acid-base reaction technique, the acid and base are neutralized, producing salt and water. By using the liquid-liquid extraction method, two different liquids were isolated based on their solubility in two liquids. Following that, and using the procedures in the instructions reference below, 2.9 mg of benzoic acid were recovered, with a percent recovery of 5.9% and a melting point range of 120.7 oC- 124.1 oC. 30 mg benzocaine were recovered. For 9-flourenone, we got 43 mg of a yellow semi solid layer that had a melting point range of 67.1 oC- 72.8 oC and an 80.7% recovery. On the other hand the benzocaine had a 64.0% recovery and a melting point range of 88.9 oC- 91.9 oC.
Procedure:
We followed the instructions making no changes or deviations.

The peaks for the functional groups are 1678 cm-1 for the C=O, 1289 cm-1 and 1453 cm-1 for C-O, 2555 cm-1, 2671 cm-1 and 2827 cm-1for the O-H, and 1583 cm-1 for the Benzene ring. The peaks strength in the C=O are strong while the peak in the C-O are not only strong, but also sharp; they are usually hard to distinguish as it is in usually found in the fingerprint region. Moreover, the peak strengths for the O-H group are broad peaks that can be medium in strength. Finally, the peak strengths for the Benzene ring are typically
