Ethyl 3‐hexenoate was oxidized for 6 hr at 150 C. The “mor volatile” fraction was swept out of the oxidizing flask and into a cold trap. The “less volatile” products remaining in the oxidizing flask were isolated by direct injection onto a preparative‐scale gas chromatographic column followed by trapping in glass capillary tubes. The decomposition products were identified by gas chromatography, mass spectrometry, infrared spectrophotometry, and chemical derivatization. The major products included epoxy esters, unsaturated keto‐ and hydroxy‐esters, and dehydrodimers. Aldehydes, short chain esters, and ketones were produced less abundantly. No aldehyde esters were detected.
