Surface-Catalyzed Reaction of the Gases Hydrogen Chloride and 2-Butyne

Article abstract of DOI:10.1021/jo00096a058

Mixtures of gaseous hydrogen chloride and gaseous 2-butyne at total initial pressures less than 500 Torr, and at temperatures between 296 and 336 K, react in Pyrex IR cells (NaCl windows) to yield only (Z)-2-chloro-2-butene, i.e., the product of net trans (or anti or antarafacial) addition.Kinetic measurements have been made by observing the reaction throughout its course utilizing FT-IR spectroscopy.It is concluded that surface catalysis is required for product formation and that the reaction is occuring at the walls.
