Conclusions
-
1.
Data were obtained on the rates of hydrogenation and isotopic exchange with deuterium of benzene and its alkyl derivatives, permitting a comparison of the basic principles of these processes.
-
2.
In the transition from one hydrocarbon to another, the rate of hydrogenation varies in the sequence: benzene > ethylbenzene > toluene > m-xylene ≈p-xylene ≈o-xylene > mesitylene, but no regular variations of the rates of isotopic exchange, both in the aromatic ring and in the methyl groups, are observed.
-
3.
The comparison made indicates different mechanisms of the two processes.
