Mixtures of the gases hydrogen chloride and (E)-2-butene, hydrogen chloride and (Z)-2-butene, and hydrogen chloride and (Z)-<2.3²H2>-2-butene at total pressures up to 7 atm and temperatures between 283 and 313 K react to yield, exclusively, 2-chlorobutane (erythro- and threo-<2,3-²H2>-2-chlorobutane in the case of the labeled alkene).Kinetic measurements for the reaction of all three gaseous alkenes with gaseous hydrogen chloride have been made by infrared spectroscopy.Elimination stadies were performed on the <2,3-²H2>-2-chlorobutane formed.It is concluded that sur face catalysis is required for product formation and that surface adsorption of both hydrohen chloride and butene is required to consummate the reaction.
