Dehydration of 2-propanol over molybdenum oxide treated with hydrogen

Article abstract of DOI:10.1246/cl.1997.1261

Dehydration of 2-propanol was carried out at 398 K using molybdenum oxides as a catalyst. The parent MoO₃ exhibited a low activity. H₂ reduction at 623 K increased the dehydration activity. After the reduction for 4 h, the MoO₃ became more active than USY zeolites, although the catalytic activity of MoO₃ declined with time on stream. We suggest that the acidity of MoO₃ was enhanced by H₂ reduction at 623 K.
