✦ Synopsis

Hydrocarbons of C 2, diluted m argon, have been pyrolysed behind incident shock waves in the range of conditions 1-12 bar pressure and 1500-2500 K temperature. The formation of carbon particles, detected both by emilion and lau, r-extinction techniques, occurred after an induction period. The effects of variation of temperature and molar density of the hydrocarbon on the induction time have been investigated. with the outcome that new correlations of data are presented, together with further insights into the reaction mechanisms involved.

EXPERIMENTAL METHODS

Two shock tubes were employed for this invest:ration, a 57-ram-alia tube at Rolls-Royce, Derby, and a 127-mm-dia tube at Nottingham University. Plastic film ("Melinex") diaphragms with cold

## Abstract Cyclohexane (cC~6~H~12~) plays an important role in the combustion of practical liquid fuels, as a major component of naphthenic compounds. Therefore, the pyrolysis of cyclohexane was investigated by measuring the formation of H‐atoms. The thermal decomposition of 1‐hexene (1‐C~6~H~12~)
