Team discovers unsuspected intermediates in the chemistry of combustion
This machine, and a similar device operating at the National Synchrotron Radiation Laboratory in Hefei, China, investigates molecules sampled from flames by combining mass spectrometry with ionization by vacuum-ultraviolet light emitted from a synchrotron. One key capability of the machines is that they are able to distinguish isomers - molecules made of the same atoms but in different arrangements - that can have very different chemical characteristics. Enols are less-stable isomers of other well-known combustion intermediates.
They were found when the team was looking for signatures of different isomers in flames. With this finding, enols can be added to predictive computer models currently used to improve combustion efficiency and cleanliness.
The unanticipated detection of enols could also have a significant impact in refining models used to describe fuel cell operation and emission-free waste cleanup using supercritical water oxidation, said Taatjes. Astronomers have also observed ethenol (one of the enol compounds now identified in flames) in interstellar space. The new enol findings may provide clues as to how complex organic molecules form in interstellar space.
