http://classes.kvcc.edu/chm230/MIXED%20ALDOL%20CONDENSATION.pdf 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.
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 … WebDibenzalacetone by Aldol Condensation 39. 10.
