Hi,
Recently i was task to synthesis Dibenzylideneacetone by adding a solution of sodium hydroxide in water and ethanol into another solution of benzaldehyde and acetone in ethanol. However, something when wrong during the recrystallization step, the initial product (Dibenzylideneacetone, yellow) was dissolved in a solution of ethanol and heated, the solution turn into dark brownish in colour and the final product was light brown powder instead the expected pale yellow crystal.
Could someone help in identifying the problem, i could not seem to find a reason for my final product being light brown powder instead the expected pale yellow crystal. Any help will be appreciated. Thank you
