低碳醇一步合成异丁醛的研究

Isobutyraldehyde (IBA) is an important organochemicals, but now there aren’t industrialized ways of synthesizing directly isobutyraldehyde. So developing technique of synthesizing IBA in one-step has very important meaning. Isobutyraldehyde is synthesized from methanol and ethanol over titanium oxide-supported vanadium oxide and titanium oxide catalysts. The finding shows that vanadium oxide has primary catalysis, but vanadium oxide must exist in special dispersion state. When 350℃ and space velocity3 h-1, catalyst shows a better performance in terms of total conversion and product selectivity.
