Summary

  1. 1.

    The mechanism of the hydrogenation of 2-methyl-1-buten-3-yne over Raney nickel was studied.

     
  2. 2.

    2-Methyl-1-buten-3-yne is hydrogenated nonselectively. The isopentane formed in the first stage of the process and part of the isoamylenes are formed directly from 2-methyl-1-buten-3-yne without passing through the intermediate stage of the desorption of isoprene into the bulk liquid phase.

     
  3. 3.

    Isoprene is displaced to a considerable extent from the catalyst surface by 1-pentyne and by 2-methyl-1buten-3-yne.
