Abstract
Conversion at low temperature of double labeled butane, (CH3CH2CH2CH3) -C-13-C-13, over sulfated zirconium dioxide modified with iron and man ganese ions, leads to isobutanes containing zero, one, two, three and four C-13 atoms in abundances corresponding to a binomial distribution . Isomerization over this catalyst apparently involves oligomerization and beta-fission of a chemisorbed C-8-carbenium ion to iso-C-4 fragme nts.
