The reaction of fluorine with n-dodecane adsorbed on porous aluminium fluor
ide (PAF) proceeds with up to 90% selectivity for all monofluorinated dodec
ane and more than 30% selectivity for terminal fluorinated dodecane, which
provides a novel means for preparing mono and terminal linear fluorinated a
lkanes. In the reaction, PAF with a large surface area is chosen as support
to adsorb the linear hydrocarbon. (C) 1999 Elsevier Science S.A. All right
