Reflected shock waves allowed temperatures from 1230 to 1800 K and pressures from 7.3 to 9.5. atm to be obtained. These measurements have shown that cyclopentane is much less reactive than. cyclohexane, as for a given temperature the observed autoignition delay times were about ten times. higher for the C5 compound compared to the C6. Detailed mechanisms for the combustion of cyclohexane and cyclopentane have been proposed to.
