摘要

A sample of 5 mM naproxen in methanol or ethanol was photoirradiated with a Hanovia 200 W high-pressure quartz Hg lamp. In total, 6 photoproducts derived from each sample were observed from the HPLC chromatograms. Four major photoproducts were separated, and their structures elucidated by EI-MS and various spectroscopic methods. A reaction scheme of naproxen in alcoholic solvents is proposed: the photochemical reaction routes occur mainly via decarboxylation and esterification, followed by oxidation with singlet oxygen to produce an alcohol and a ketone.
