摘要

A brown liquid oxovanadium(V) alkoxide [VO(OCH(CH_3)CH_2OCH_3)_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 ~51V 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.
