General description

2,3-Dimethylbutane can can undergo hydrogenolysis over supported catalysts of ruthenium, nickel, cobalt, and iron to form smaller hydrocarbons, mainly methane.

Application

  • Synthesis, structure, and properties of the condensation product of hexaoxocyclohexane with 2, 3-bis (hydroxyamino)-2, 3-dimethylbutane: Discusses the chemical synthesis and structural analysis of a novel compound derived from hexaoxocyclohexane and 2,3-dimethylbutane (EV Tretyakov, AO Tkacheva, 2014).
  • Catalysts by design - Surface organometallic chemistry on oxide and metal for dehydrogenation of 2, 3-dimethylbutane: This paper details the development of a selective catalyst system for the dehydrogenation of 2,3-dimethylbutane, emphasizing the stability and efficiency of the catalyst (P Rouge, A Garron, S Norsic, C Larabi, N Merle, 2019).
