Kinetische Untersuchungen zur Pyrolyse von Mono‐n‐alkyl‐cyclohexanen

Abstract

Kinetic Investigations of the Pyrolysis of Mono‐n‐alkyl‐cyclohexanes The thermal decomposition of cyclohexane and six mono‐n‐alkylcyclohexanes was studied kinetically in a metallic laboratory tubular reactor at 650 to 850°C and atmospheric pressure. Kinetic parameters were found to be a function of length of the alkylic side chain. A comparison with analogous parameters of n‐paraffins and the unsubstituted cyclohexane allowed the conclusion that CC‐scission in the alkylic chain is the initial reaction in pyrolysis of n‐alkylcyclohexanes followed by radical attacks to all CH‐bonds of the feed molecules.
