摘要：

A brown liquid oxovanadium(V) alkoxide [VO(OCH(CH3)CH2OCH3)(3)](n) was prepared by heating under reflux ammonium metavanadate with alcohol and toluene. The exchange processes between monomer and oligomers in pure or diluted medium were observed by dynamic V-51 NMR study. The compound reacted with magnesium 1-methoxy 2-propanoxide to yield in situ a heterobimetallic alkoxide, which is used in the synthesis of a vanadium-magnesium oxide catalyst. Textural and structural properties of the resulting oxide have been presented. (C) 2001 Elsevier Science Ltd. All rights reserved.
