Kinetic isotope effect in trans-alkylation with ethylbenezene

Autor: O. R. Sergeeva, V. G. Lipovich, V. V. Chenets

Publikováno v: Reaction Kinetics and Catalysis Letters. 19:411-414

Kinetic isotope effect (KIE) measurements in the trans-alkylation of toluene and benzene with ethylbenzene in hexane in the presence of AlBr3 at 313 K indicate that deuterium in the toluene methyl group causes a small inverse KIE characteristic for a

Publikováno v: Reaction Kinetics and Catalysis Letters. 22:287-291

The activity and selectivity of bimetallic Pt−Pb catalysts and their stability in n-pentane isomerization have been studied. Up to 25% Pb concentrations, the isomerization rate is shown to remain unchanged whereas that of hydrogenolysis decreases.
