Unformatted text preview: Experiment 10: “Green” Oxidation of Aromatic Aldehydes Chem 2510 Introduction : In this experiment, benzaldehyde was oxidized to benzoic acid in water using Oxone (contains 2:1:1 molar ratio of KHSO 5 , KHSO 4 , and K 2 SO 4 ) as the oxidizing agent. In this reaction, environmentally benign solvent (water) and a non-toxic, nonpolluting oxidant (Oxone) was used to effect the chemical reaction in a “green” manner. Results and Discussion: Reflux was performed using benzaldehyde, Oxone, and water (Table 1). The acid product was collected by vacuum filtration and by rinsing the solid product with minimum amounts of cold water. The solid was allowed to dry. The melting point range and mass of the crude solid were determined (Table 2). The crude product was recrystallized from hot water (19.5 mL hot water were used) and collected by vacuum filtration. The solid was allowed to dry. The mass, percent yield, and melting point range of the recrystallized product were determined and an IR...
