WebArab American University Digital Repository (AAUPSpace): Home 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.
