Article abstract of DOI:10.1021/j100412a091

Mixtures of gaseous hydrogen chloride and gaseous 2-methylpropene at total pressures less than 1 atm yield, exclusively, gaseous 2-chloro-2-methylpropane.Kinetic measurements have been made by proton magnetic resonance and infrared spectroscopy and by observing the pressure change accompanying the reaction.It is concluded that surface catalysis is required for product formation and that the reaction, which occurs at the walls, is most probably between strongly adsorbed hydrogen chloride and weakly adsorbed 2-methylpropene; i.e., a Rideal-Eley mechanism obtains.
