Abstract
The adsorption isotherms of n-butane and butene-1 on typical furnace and channel carbon blacks were determined over a range of temperatures, 55°–250 °C. The adsorption of n-butane on carbon black surfaces is attributed to physical adsorption; however, the extent of surface covered per unit area of carbon black is considerably greater at a given temperature than for a silica. Butene-1 is also physically adsorbed on the furnace blacks. The presence of approximately 3% chemisorbed oxygen on the surface of the channel blacks induces an isomerization of butene-1 to cis-butene-2. When oxygen is first chemisorbed on a furnace black surface, then that surface also interacts with butene-1. Those blacks which participate in the isomerization of butene-1 respond or "interact" in a cyclic heat treated Butyl rubber – carbon black masterbatch.Keywords
