Abstract
The CO2 cw laser powered homogeneous pyrolysis (LPHP) of acetone, 2,3-butanedione and cyclobutanone (all 1.3 - 4kPa) sensitized by sulphur hexafluoride (0.7-1.3kPa) was investigated. The decomposition course of the ketones is analogous to that occuring under conventional pyrolytic conditions. The decomposition rate and the product composition are affected by laser power, partial pressure of the sensitizer, and the buffer gas (helium) added. Besiedes the conventional pyrolytic products, the LPHP of acetone and 2,3-butanedione affords acetylene and that of cyclobutanone produces acetic acid. A possible reaction mechanism of the decompositions is discussed.
