Dibenzalacetone by the aldol condensation
WebDrucillah Nalukwago Introduction This is a mixed condensation reaction (Claisen condensation). Dibenzalacetone is prepared by using 2 moles of benzaldehyde and acetone. The aldehyde carbonyl is more reactive than that of acetone therefore it reacts rapidly with the anion of the ketone forming a beta-hydroxy ketone, which can easily … WebAim: 1-Aldol condensation is an important route of organic synthesis because it provides an efficient way to form carbon-carbon bond. Flowchart: Mix 5.306g of benzaldehyde and …

WebNumerade. SOLVED: EXPERIMENT Synthesis and characterization of dibenzalacetone Purpose this experiment You will synthesize dibenzalacetone by using aldol condensation reaction: The product will then be recrystallized and characterized by mp: and IR analysis: WebThe purpose of this experiment was to carry out an aldol condensation to produce dibenzalacetone and determine which of the three possible isomers of dibenzalacetone (cis,cis, cis,trans, and trans,trans) is the major product. The recorded melting point was 84°C, which is close to cis, trans (Z,E) dibenzalacetone with melting point of 60°C.
