Objective : the purpose of this experiment was to study the thermodynamics of an esterification reaction and then use titrations determine the concentrations of reactants/products before and after the reaction. Finally, a K eq calculation was to be made. Table of Pertinent Physical Properties Overall Reaction O + CH 3 CH 2 CH 2 OH H + O + H 2 O acid ester alcohol CH 3 -COH CH 3 -COCH 2 CH 2 CH 3 . Procedure Into a clean, dry, 100 mL round bottom flask (RBF), add 0.25 moles of glacial acetic and 0.25 moles of n-propanol were added; the flask was mixed thoroughly by swirling. 1.00 mL (use a graduated pipette) of the reaction mixture was transferred to a 125 mL conical flask containing about 25 mL of deionized water and 2 drops of phenolphthalein indicator. This flask was labeled “Number 1”and was stoppered and set aside. 8-10 drops of the acid were added to the reaction mixture in the RBF and the exact number of drops added Substance (include Structure) M.F.
