In this exercise, we synthesize vanillyl alcohol from vanillin by dissoliving the vanillin in aqueous base and reacting it with excess sodium borohydride. Any unreacted sodium borohydride is converted to boric acid by reaction with hydrochloric acid. The product is filtered and washed free of boric acid. The resultant material is analyzed by infrared spectroscopy.
The following data were collected in the synthesis of Vanillyl Alcohol from Vanillin according to the procedure described in SUSB-039.
