Oxidative Dehydrogenation of Ethanol Over Mixed Metal Oxides 6 6 - - - - - - - - . - . - 0 . - . - 0 .

ABSTRACT Oxidative dehydrogenation of ethanol to acetaldehyde and acetic acid is studied in heterogenous catalytic system over the catalysts containing varying proportion of antimony oxide in the mixture of tin and molybdenum oxides considering lower explosive limit. About 20% mole of Sb204 is shown to have excellent activity for partial oxidation of ethanol to acetaldehyde and acetic acid at 280oC. There is complete ethanol conversion up to 20 mole % Sb204, increase in W/F increases selectivity towards acetic acid. Further increase in the proportion of Sb204 shows increase in selectivity towards acetaldehyde whereas there is no substantial change towards the selectivity of acetic acid.
