Abstract

Catalytic dehydrogenation of iminodibenzyl to iminostilbene was carried out at 550°C on a binary oxide system of Mn₂O₃-SnO₂. Maximum activity was observed at an Mn₂O₃-SnO₂ ratio of 8 : 2 ; conversion was 40%, selectivity 82%. Mn₂O₃-SnO₂ catalyst dispersed on MgO and modified with K₂CO₃ gave 80-90% conversion and 82-88% selectivity. The relation between activity and the physical properties of catalysts was studied.
