“…Indeed, the process is favored by a permanent supply of HCl. Indeed the alumina surface may accommodate the HCl in a number of ways, dissociative or not, with a broad spectrum of desorption energies [20,22,23]. The TPD measurements amply confirm the occurrence of weakly and tightly bound Cl on our samples.…”

“…In fact, the surfaces of SRM exhaust particles have been found to contain inorganic chlorides, presumably from reaction with HC1 in the exhaust plume [Cofer eta!., 1989]. Previous work on alumina catalysts suggests that these surfaces should be more reactive than pristine aluminum oxide toward halocarbon adsorption [Thomson et al, 1991]. Finally, SRM exhaust particles also may be quite porous and thus contain far more surface area than assumed in these calculations.…”

“…The reaction occurs also in the presence of solid aluminium trichloride that has been resublimed in vacuo; it consists of a rapid dehydrochlorination of CH 3 CCl 3 to give CH 2 CCl 2 followed by oligomerisation of the latter and further loss of HCl from the oligomeric mixture that coats the solid AlCl 3 surface [37]. Similar, though less violent, chemistry occurs when g-alumina, which has been chlorinated by CCl 4 in order to promote its surface Lewis and Brønsted acidity, is exposed to CH 3 CCl 3 [38]. Not surprisingly, g-alumina that has been fluorinated by SF 4 is also a suitably acidic surface on which to perform the chemistry.…”
