The properties of dibenzalacetone make it a great substance to be used when protecting the skin from the sun. In the experiment performed‚ dibenzalacetone was created from an aldol condensation of 2 portions of benzaldehyde and acetone in sodium hydroxide. The reaction that occurred in this experiment is known as a specific aldol condensation called Claisen-Schmidt. In the reaction‚ the carbonyl of benzaldehyde reacts quickly with the acetone anion to create a hydroxyketone that dehydrates in the

flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be compared.

color change from dark purple to tan was observed. Upon cooling‚ ethanol (3 mL) was added and the soln was shaken to facilitate combination. The tan soln was then placed in an ice bath to cool for 10 min. The solvent was removed from the solid under vacuum filtration and washed with cold ethanol to retrieve a white precipitate.

nonpolar molecules can participate in as well due to the transient dipole moments that exist in them. In the solid-liquid extraction‚ a solvent is added to a mixture of solid compounds. A specific compound in the mixture will dissolve in that solvent. Vacuum filtration can then be used to separate the specific compound from the other compounds in the mixture‚ which are insoluble in that solvent. In the liquid – liquid extraction‚ you must have solvents that are immiscible (organic and aqueous). The solvents
