Abstract

The exfoliation-reduction of VOPO4·2H2O in l-butanol oriso-butanol alone, and in a l-butanol/ethanol oriso-butanol/ethanol mixture, were conducted. Although all precursors were composed of a lamellar compound with intercalated alcohol molecules, VOHPO4·0.5H2O was formed when the exfoliation-reduction process was carried out in the mixed alcohol. All precursors transformed to a single phase of (VO)2P2O7 under the reaction conditions forn-butane oxidation, but the crystallinity of (VO)2P2O7 was different. The catalyst synthesized iniso-butanol/ethanol was well crystalline (VO)2P2O7, and exhibited higher selectivity to maleic anhydride than that synthesized iniso-butanol alone for then-butane oxidation.
