Esterification and IR Spectroscopy #3

The contents were transferred into a centrifuge tube that contained water (1 mL) and was mixed thoroughly with a pipet before the lower aqueous layer was removed. Saturated aqueous sodium bicarbonate (1 mL) was added and mixed thoroughly with a pipet before the lower layer was removed. This was repeated once more with sodium bicarbonate (1 mL). The step was then repeated with saturated aqueous sodium chloride (1 mL). To a vial was added the organic layer and 5 spheres of calcium chloride. The vial was then swirled gently. Afterwards, the liquid was transferred into a dry tared capped vial and the odor was observed. The IR spectroscopy was then determined.
