Caption: Crystallization of dibenzalacetone. Time-lapse footage of the final crystallization stage of an experiment to produce the organic compound dibenzalacetone. This chemical was formed by reacting benzaldehyde with acetone, in what is known as an aldol condensation reaction. The product shown here has been through several stages of washing and recrystallisation to purify it. This solution in ethanol is now cooling down and as it cools, crystals of dibenzalacetone (yellow) form within the liquid. Dibenzalacetone is used in sunscreens and as a reagent in organometallic chemistry.
