Ester synthesis procedure 2

           For the work-up, the cooled contents of the rb flask were transferred into a centrifuge tube containing water (1.0 mL, 56.0 mmol). The layers were mixed thoroughly, allowed to resettle, and then the lower aqueous layer was removed into a beaker marked for waste. Saturated aqueous sodium bicarbonate (1.0 mL, 5.4 mmol) was added, the layers were mixed thoroughly the lower aqueous layer was removed into waste.This process was repeated. Saturated aqueous sodium chloride (1.0 mL, 7.9 mmol) was added, the layers were mixed thoroughly, and the lower aqueous layer was removed to waste. The organic layer was transferred into a vial, and five spheres of anhydrous CaCl2 were added to the mixture and swirled until no clumping occurred, then left to stand for about five minutes. The liquid was transferred to a dry, tared vial. The odor was noted, the final mass was measured and recorded,  and IR spectroscopy was performed.
