n-Decane has been pyrolysed at 700�C. Fifty-two compounds have been identified in the resulting tar. Mechanisms of formation are discussed.

Pyrolyses of inactive and of 14C-labelled 2-methylstyrene at 700� are reported. Sixteen compounds were identified in the tar obtained following pyrolysis of the inactive compound, and nine of these were isolated in sufficient purity and yield for radiochemical analysis following pyrolysis of the labelled compound. Probable mechanisms of formation of these compounds are discussed.

The pyrolysis of n-[σ-14C]propylbenzene at 700� has given a tar from which nine compounds have been isolated in sufficient quantity and purity for radio- chemical analysis; four of these have been degraded to determine the distribution of the radioactivity. Evidence is presented that there is an effective partial interchange of α and β carbon atoms in the formation of styrene, and probable mechanisms of formation for this, and other, compounds are discussed.

The pyrolysis of [l-14C]styrene at 710� has given a tar from which nine compounds have been isolated in sufficient quantity and purity for radiochemical analysis. Four of these have been degraded to determine the distribution of the activity, and the results are discussed with reference to possible mechanisms of formation from styrene.


In the first paper of this series (Burgoyne 1937) the kinetics of the isothermal oxidation above 400° C of several aromatic hydrocarbons was studied. The present communication extends this work to include the phenomena of ignition in the same temperature range, whilst the corresponding reactions below 400° C form the subject of further investigations now in progress. The hydrocarbons at present under consideration are benzene, toluene, ethylbenzene, n -propylbenzene, o-, m - and p -xylenes and mesitylene.

The pyrolysis of anthracene at 700� has given a tar containing ten polycyclic hydrocarbons all of which are probably formed by the scission of carbon-hydrogen bonds to give anthryl radicals followed by further reaction with anthracene. The pyrolysis of anthracene at 950� gave a much more complex tar in which 25 aromatic hydrocarbons have been identified. The major constituent was found to be phenanthrene. It is suggested that this is formed via tetrahydroanthracene and tetrahydrophenanthrene. It is also suggested that the complexity of the tar is due to the scission of the saturated carbon-carbon bonds in tetrahydroanthracene and tetrahydrophenanthrene, followed by further reaction of the fragments.

n-Butylbenzene has been pyrolysed over a range of temperatures from 300� to 900�, at 50� intervals, and the resulting tars analysed. The optimum temperatures for the formation of 15 polycyclic aromatic hydrocarbons have been determined; these range from 660� to 740�.
