Procedure
acetone (1 mL). Add ethanol (5 mL) and stir the mixture. Carefully add 10% sodium
To a 100-mL Erlenmeyer flask equipped with a stir bar add furfural (3 mL) and
hydroxide solution (2 mL) and continually stir the mixture for 1 h, note any changes.
stirring bar from the aldol reaction using a magnetic retriever or a spatual and place
Place a 500 mL beaker containing water-ice (300 mL) in an ice bath. Remove the
the bar in the beaker. Stir the solution vigorously. Using a glass pipette, add
dropwise the reaction mixture. This must be done very slowly and with vigorous
stirring to prevent oiling out of the product. If the product oils out, you will not be
able to filter it after stirring vigorously for an additional hour! You may also need to
use a stirring rod.
After the addition, make sure that there is no oil in the bottom of the beaker. If there
is, continue stirring. Filtering oils will clog the filter paper. Vacuum filter the solids
using a large Buchner funnel. Wash the solids with ice-cold water. Let the solids air-
dry. The weight of your sample will be taken in the next lab period after it has dried.
Characterization
Obtain a 'H NMR of the dry product. There are no purification methods in this
experiment and there are four possible products. However, one of these products
predominate. Decide from the NMR which of the four this is (hint: a driving force of
the reaction is conjugation).
