✦ Synopsis

The very low-pressure pyrolysis (VLPP) technique has been applied to the pyrolysis of di-t-amyl peroxide (DTAP) over the temperature range 523-633°K. VLPP yields a low-pressure rate constant, kuni The conversion of k,,, to k, , which must be made to calculate the Arrhenius parameters, is accomplished via the R R K M theory. The transition state model used in the R R K M calculations was based on a transition state model which accurately reproduced the VLPP data for di-t-butyl peroxide for which the Arrhenius parameters are well known. For the decomposition of DTAP it was found that log k,(30OoK) = 15.8 -36.4/s, where e = 2.303RT, in kcal/mole, and the units ofk, are sec-'.

The pyrolysis of ethyl acetate has been studied by the very low-pressure pyrolysis (VLPP) technique. The results obtained agree well with the previously determined high-pressure Arrhenius parameters where log k, = 12.6 -48.0/8. The rate constants given by these parameters have also been shown to be

The thermal unimolecular decomposition of pent-2-yne has been studied over the temperature range of 988-1234 K using the technique of very low-pressure pyrolysis (VLPP). The main reaction pathway is Cd-Ch bond fission producing the resonance-stabilized 3methylpropargyl radical. There is a concurrent
