Triphase Catalytic Reactions
Using Clay Intercalates
N\1 Shabestary\2\2 S\1 Khazaeli\3 and N\1 Long\3
A naturally occurring clay mineral\1 hectorite\1 was used as the support for quaternary ammonium
cations\2 The intercalation of the cations by the clay has the advantage of separation of the
catalyst from the product by a simple \3ltration technique\2 Several quaternary ammonium cation
clay intercalates have been used to investigate the e\4ects of alkyl chain length\1 size and shape of
these catalysts in converting n\5butyl bromide to n\5butyl chloride\2 It appears that the hectorite
intercalates have a great tendency for emulsi\3cation in the presence of organic solvent \x06toluene\7
and water\2 In fact\1 the emulsi\3cation being facilitated by the clay intercalates helps to bring the
nucleophile from the aqueous phase into contact with the substrate\1 which is contained in the
organic phase\2 The rate of the reaction was measured for the biphase reaction \x06no supporting
clay\7 and for the triphase catalytic system \x06with supporting clay\7 for comparison\2 Relatively
large di\4erences in reactivity have been observed between the catalysts chosen in this research\2
The results have indicated that quaternary ammonium with certain carbon numbers has higher
catalytic activity\2
