A comparative study of acid-base properties and catalytic activity of Sn-La and
Sn-Sm mixed oxides and their corresponding sulfate modified analogues are
reported in this thesis. The catalytic activity and product selectivity in the
decomposition of alcohols are correlated with the acid-base and redox properties
of the catalyst systems under study The effect of catalyst preparation,
pretreatment and various reaction parameters on the catalytic activity of sulfate
modified oxides is investigated in the oxidative dehydrogenation reactions The
experimental conditions are optimised to synthesise industrially important organic
chemicals viz. 2,6 xylenol, o-cresol, N-methylanilne and N,N-dimethylaniline
employing the mixed oxide systems. The effect of sulfate treatment on the
catalytic activity of these systems in the alkylation reactions of phenol, anisole and
aniline is also investigated and the merits and demerits of sulfate treatment are
highlighted. |
