WebMar 2, 2024 · The yield is 105–110 g. (90–94 per cent of the theoretical amount) (Note 5) of a product which melts at 104–107°. The crude dibenzalacetone may be recrystallized from hot ethyl acetate, using 100 cc. of solvent for each 40 g. of material. The recovery in this purification is about 80 per cent; the purified product melts at 110–111°. WebThis "nucleophilic" carbon then attacks the carbonyl carbon of the cinnamaldehyde, resulting in a new carbon-carbon bond. The process the repeats with the formation of a carbanion on the alpha carbon that was originally on the other side of the acetone carbonyl group. The final product is 1,9-diphenyl-1,3,6,8-nonatetraen-5-one (dicinnamalacetone). grade 12 mathematics june exam papersWebDicinnamalacetone.
