Abstract
Photolytic oxidation of acetic and propionic acids by aqueous sodium hypochlorite has been studied. In the presence of excess of sodium hypochlorite, these acids were photo-oxidised effectively to CO2 and H2O, but the reaction did not occur in the dark. By contrast, irradiation of an equimolar mixture of propionic acid and sodium hypochlorite gave the oxygenated products CH3CH(OH)CO2H, HOCH2CH2CO2H, CH2(CO2H)2, CH3COCO2H, CH3CO2H, HOCH2CO2H, and CO2 together with small amounts of the chlorinated products CH3CHClCO2H, ClCH2CH2CO2H, and ClCH2CO2H. The chlorination products were favoured at lower wavelength (e.g. >300 nm). Secondary photo-oxidation of these products was also studied and the reactivities are discussed.Keywords
