摘要：

Niobic acid is a unique catalyst with moderate acid strength and water- resistance property. As a result of its properties, niobium oxide exhibit unique activity, selectivity and stability for many different catalytic reactions,for example, olefin hydration, alcohol dehydration, and alcohol esterification[1,2]. In this paper, Nb2O5 was used as the starting material, and HP used as the support. First, Nb2O5 was mixed with Hβ in a given ratio, then grinded followed by microwave irradiation or calcination at 773K. Several preparation variables and reaction conditions were studied. Dehydration of isopropanol was carried out in a fixed-bed reactor. The reaction products were analysed by GC.
