Comments:   The pyrolysis of acetadehyde and its isotopomers (CH3CDO, CD3CHO, and CD3CDO has been studied using a high temperature, microtubular SiC reactor. Product detection was via both photoionization mass spectrometry and matrix isolation infrared spectroscopy. The initial principal unimolecular processes appear to be radical decomposition and isomerization of acetaldehyde to vinyl alcohol.
