Summary

  1. 1.

    The catalytic transformations of cyclopentane, methylcyclopentane, and ethylcyclopentane were studied in presence of platinum deposited on aluminum silicate under atmospheric pressure at 200–270°.

  2. 2.

    In the range 200–235° the hydrogenolysis of cyclopentane and methylcyclopentane goes selectively, which makes it possible to determine the apparent activation energies of these reactions.

  3. 3.

    For ethylcyclopentane conditions could not be found under which hydrogenolysis goes selectively. Under the given conditions the main direction taken by the transformations of ethylcyclopentane is its isomerization to methylcyclohexane.

  4. 4.

    The temperature coefficient of the isomerization reaction is lower than that for the dehydrogenation of methylcyclohexane. In the range 230–270° the extent of the hydrogenolysis of ethylcyclopentane diminishes some-what with rise in temperature.
