Abstract
trans-Anethole is a photosensitive molecule of interest to the food industry and it is a component of many essential oils. However, trans-anethole can easily isomerize to the cis- isomer, which is recognized as toxic. A solution of transanethole in toluene was irradiated with a UV lamp. The products of the photoreaction were analyzed by gas chromatography and mass spectrometry. The quantum yields of the trans- cis- anethole isomerization reaction at 4 and 15 oC were 0.67 and 0.17, respectively.
