The p-anisalaldehyde solution was then added drop wise with the pipet to the acetone and NaOH solution for a given period of time before the next drop was added to view that the solution was mixed well. The response was stirred well for 25 minutes. The color change of the solution provided the viewable indication of the product formation. At the end of the experiment, the stir veto was returned to the instructor and left the magnetic stirrer on the table. In the Dianisalacetone synthesis, acetone was used as a reagent in the reaction. During the experiment, 3 mL of aqueous NaOH solution was added to 25mL flask then later on 10 mL of acetone was added. The flask was then place on the magnetic stirrers of the bench and then stirred. 1 mL of p-an isalaldehyde was then dissolved in 10 mL of ethanol into the beaker and then swirled to mix the reactants well. The p-anisalaldehyde solution was then added drop wise with the pipette to the acetone and NaOH solution for a given period of time before the next drop was added to control that the solution was mixed well. The reaction was stirred well for 20 minutes. At the end of the experiment, the stir bar was returned to the instructor and left the magnetic stirrer on the table. To find the isolation and purification of Anisal or Di-Anisalacetone, the reaction mixture was diluted in the Erlenmeyer flask 10mL of tap water. After submitting to the supervisor, the diluted mixture was then transferred to the separatory funnel shape found at the HOODS. After draining the yellow organic layer, the solution was later dried with the anhydrous sodium sulfate and then filtered into the round bottom flask. The solvent was later removed with the help of the carrousel evaporator and water bath found at room temperature. The
