The isomerization, dehydrocyclization and hydrogenolysis of 3-methylhexane have been studied at 320-380 deg C over a series of Pt-Al2O3 catalysts with a metal dispersion extending from 0.05 to 1.The use of five labelled compounds, 3-methyl(1-(13)C), (2-(13)C), (3-(13)C), (6-(13)C)hexanes and 3-methyl((13)C)hexane, alloved distinction between the various parallel pathways.On all catalysts the predominant reaction was the isomerization according to a cyclic mechanism involving either 1,3-dimethyl-, 1,2-dimethyl- or ethyl-cyclopentane intermediates with a relative contribution of 60, 40 and 20 percent, respectively.These results are consistent wiith a dehydrocyclization scheme involving a metallocarbene as precursor and dicarbene or dicarbyne recombination as the rate-determining step.
