Dibenzalacetone by the aldol condensation
WebMay 15, 2003 · The aldol condensation reaction between acetone and benzaldehyde was successful and yielded dibenzalacetone. The percent yield for this reaction was 59.48%. This was low due to the fact that many crystals were lost during the removal of the solvent from the reaction mixture in Part 1. Some crystals were also lost during the washing of … WebDibenzalacetone by Aldol Condensation 49 ALDOL SYNTHESIS of DIBENZALACETONE, AN ORGANIC ( SCREEN Overview: The reaction of an aldehyde …
