Aldol Condensation- Synthesis of Dibenzalacetone

The protocol says that, after adding in all the reactants, stir for an additional 15 minutes.  A student swirled for only 8 minutes and then, correctly, stopped and proceeded with isolating the product.  What did the student do that gave such confidence and accuracy?

 

The reaction ofa ketone with an aldehyde in the preserice of a strong base is an example of a mixed
aldol condensation (Claisen-Schmidt reaction). In this example, acetone reacts with two
equivalents of benzaldehyde to give dibenzalacetone. As with other condensation reactions, H2O
is a by-product of the reaction.
