✦ Synopsis

The high-temperature decomposition of propylene has been investigated in a single-pulse shock tube in the temperature range 1160-1700 K. The stable products observed were hydrogen, methane, ethylene, acetylene, ethane, allene and propyne. The rate of evolution of the different products was found to have a similar concentration-dependence except for ethane, which was found to be dependent only on the third-body concentration. A computer model of the kinetics is presented, according to which the first step of the propylene decomposition has a rate constant (calorie units) of: k,[Ar] (mol/cm3s) = (10t3+u.5) exp [(-74 f 1) X 103/RT]

## Abstract The ignition delay of __n__‐decane and oxygen diluted in argon was investigated for a series of mixtures ranging from 0.49 to 1.5% decane and 4.16 to 23.25% O~2~ diluted in argon. The temperature range was 1239–1616 K and the pressure range was 1.82–10.0 atm. All experiments were perfor
