In the previous paper (XIII), the authors found that according to the thermodynamical consideration, n-paraffins are dehydrogenated by quinones at 100150°C, and carried on experiments on this point. The authors found that n-paraffins are, in general, stable to quinones, but dehydrogenation occurs at the end with an increase in number of carbon atoms, though it is of a small quantity. The authors detected at the same time hydroquinones.
