INVESTIGATION OF THE REACTIONS OF PHENOL, ANISOLE AND CUMENE WITH O(P-3) IN THE GAS-PHASE

The rates of the reactions of phenol, anisóle and cumene with atomic oxygen in the electronic ground state have been measured in a discharge flow system with massspectrometric detection. All measurements were performed in an excess of O atoms in the temperature range 292 < T < 873K. The measured second order rate constants do not form a straight line in the log k vs. 1/T plot. In the lower part of the temperature range they can be approximated by the following expressions: (formula omitted)Some reaction channels are discussed on the basis of available thermochemical data. © by R.
