Catalytic oxydehydrogenation of 2-Ethylpyridine (cas 100-71-0)

Add time:07/20/2019    Source:sciencedirect.com

A wide variety of metal oxides and phosphates have been investigated as possible catalysts for the oxydehydrogenation of 2-ethylpyridine in the presence of steam at 773–873 K and atmospheric pressure. In general, mild oxidation-dehydrogenation catalysts showed higher yields. SnO2SiO2 proved the most interesting catalyst, with initial 2-ethylpyridine conversion near 50%, initial selectivity to 2-vinylpyridine higher than 80% and easy reproducibility. The effect of SnO2 content and of the nature of the support is discussed. Extended time runs showed a decrease of initial yield after 40 h on stream. However, air regeneration of aged catalyst led to a complete recovery of initial activity. The influence of reaction parameters, such as temperature and feed composition, has also been investigated.
