Abstract
An eco-friendly procedure for the oxidation of aldehydes to carboxylic acids in water or a water-ethanol mixture using Oxone as the oxidant is described. An easy isolation of the precipitated product upon cooling the reaction mixture helps avoid the use of extraction solvents in the product isolation procedure. The use of eco-friendly solvents, a non-toxic reagent, and the elimination of extraction solvents in the procedure demonstrate important green chemistry themes to the students. The optimized experimental procedure reported herein allows students to successfully carry out the experiment, isolate the product, and characterize the purified product through melting point determination and 1H NMR spectroscopy during a three-hour laboratory period.
