The Absolute Measurement of Rate Constants for Some Key Reactions Involving Free Radicals

The rate constant for t-butyl radical combination was determined over the temperature range 620-690K, using the very low-pressure pyrolysis (VLPP) technique. The value of the combination rate constant, and the disproportionation combination ratio, were independent of temperature. The rate constant f...

Description
Summary:The rate constant for t-butyl radical combination was determined over the temperature range 620-690K, using the very low-pressure pyrolysis (VLPP) technique. The value of the combination rate constant, and the disproportionation combination ratio, were independent of temperature. The rate constant for ethyl radical combination was determined at 843 and 878K. The high pressure absolute rate constants for the decomposition of nitrosobenzene and pentafluoro-nitrosobenzene were determined using the (VLPP) technique. The thermal decomposition of t-butylmethyl ether has been studied. See also report dated Aug 73, AD-770 689.
