✦ Synopsis
Hydrogen abstraction by 1-phenylethyl radicals (RH) from phenylmethyl-carbinol (HROH) and benzyl alcohol (H2R'OH) has been studied in the liquid phase at 120°C. 1-Phenylethyl radicals have been generated by thermal decomposition of azo-bis-lphenyl ethane and the formation of ethylbenzene (RH2), acetophenone (RO), and 2,3-di-phenyl butane (R2H2) has been monitored during the reaction.
In order to optimize the experimental conditions, a mechanism has been assumed for the various pathways of the disappearance of RH and by using estimated rate parameters a presimulation was performed.
The relative rate constants obtained are: and where kH refers'to the hydrogen abstraction while k, is the combination rate coefficient of the radicals RH.
