Synthesis of Dibenzalacetone
Objective :We want Synthesis Dibenzalaceton from Aceton and Benzaldehyde by Crestylization.
Caculation:
Mass Of Funeral Plus Product: 7.9182 g/mol
Mass Funeral : 7.0582 g / mol
Mass Of Product: 0.86 g/mol
Mass of Aceton : 0.058g/mol
O.o58g: 58.3g/mol= 9.94 mol Aceton
0.216g:106.13g/MOL=o.0020mol Benzealdehyde - Limted Reagent
0.0020molx234.30 g/mol =0.4686 g diBenzalaceton
Mass of Benzelaldeheid : o.216 g
Percent Yield:
(Actual Yield : Theorical Yield)x100% =
(0.86g: o.4686g)X100%= 40 % Percent Yield
Mp: 99”C
Mp (in the class): 110”C
Disscution:
In these experiment an ethanolic solution of acetone and Benzaldhyde add to aqueous sodium hydroxide. The product, We crystallizes product (dibenzalaceton ) after a few minute, the product is filtered from the mixture, washed, dry it. We want to find out the mass of product, after we dry it.
We put all ingredients in the test tube, we make a solution. It contain 0.058 gr Acetone and 0.216g Benzaldehyde, 1.6ml of 95% Ethanol , 2ml of 3M Hydroxide. Benzaldyde is initially in
Soluble in solution . The solution gets cloudy, after a minute, we
