Iodination of Salicylamide
Methods
In Experiment 5, two test tubes were acquired, one containing 20 mL of absolute ethanol,
and one containing 7.0 mL of NaOCl (bleach). 0.9964 g of solid salicylamide was added to a
flask and dissolved with the ethanol. After this, 1.2065 g of solid sodium iodide was added to the
solution, then stirred at 150 rpm. Once the solution reached homogeneity, it was placed in an ice
bath and cooled to 0.0°C. 7.0 mL of NaOCl was then added quickly to the solution and stirred
vigorously. As the reaction commenced, the solution took on different colors, first as a dark,
almost brown orange, the reddish orange, then a golden color, then a strong yellow, before
finally settling on the desired pale-yellow color. At this point, the solution was allowed to settle
undisturbed for 10 minutes.
