Early Kinetics

All through the war some activity was maintained in Hinsh's group in both gas-phase and solution kinetics, in addition to the studies in bacterial growth. Between the end of the war and his retirement in 1964 his interest in bacterial growth predominated, with just over one hundred papers being published, but his involvement in classical kinetics was also maintained; there were sixty-five papers in this field in the same period. The gas kinetics included work on the hydrogen-oxygen reaction already referred to, work on a wide range of pyrolytic and radical-induced processes and some studies of gas-phase oxidation.

The latest papers published from the group - on the influence of structure on the rate of oxidation of gaseous cycloalkanes, on the determination of individual rate constants in the thermal decomposition of ethane, on the inhibition and acceleration of paraffin decomposition by nitric oxide elaborate themes which had been Hinsh's concern for many years, and similarly we find papers on energy-entropy relations in acylations and on the benzoylation of substituted anilines in different solvents.
