Webb25 okt. 2013 · The percent yield for this reaction was 59.84%. This was due to loss of crystals during recrystallization and during solvent removal from the reaction mixture. The observed melting point was 104 – 107.5°C, compared to a literature value of 110°C. The lower and broader observed melting point may have been due to the product still being … WebbThe percent yield (70%) is fairly good and means the experiment was sufficiently efficient; however, the presence of impurities may mean that the actual yield may be lower than 70% taking the weight of the …

Mass of Dibenzalacetone = 10.00 grams Melting Range of Dibenzalacetone = 106-108 °C. death valley national park things to seeWebbDibenzalacetone, also known as dibenzylideneacetone or dibenzalaceton, is a chemical compound with the molecular formula C20H20O2. It is a white, crystalline solid with a faint sweet, floral odor. It is insoluble in water, but soluble in most organic solvents. One of the important physical properties of dibenzalacetone is its density. death valley national park vegasWebbDibenzalacetone is readily prepared by condensation of acetone with 2 equivalents of benzaldehyde. The aldehyde carbonyl is more reactive than that of the ketone and therefore reacts rapidly with the anion of the ketone to give a beta-hydroxylacetone, which easily undergoes based- catalyzed dehydration. death valley national park vacation rentalshttp://api.3m.com/dibenzalacetone+density death valley national park top attractionsWebb16 aug. 2024 · The melting point was found to be 108°C. the sharp melting point range indicates that the dibenzalacetone produced was very pure.
