摘要
Processes for preparing high-purity niobium alkoxides, especially niobium ethoxide, are described which include: (a) providing a crude niobium alkoxide starting material comprising at least one compound of the general formula (I)Nb(OR)5 (I)wherein each R independently represents a linear or branched C1-12 alkyl group; and (b) contacting the crude niobium alkoxide starting material with a treatment medium comprising a component selected from the group consisting of (i) one or more alcohols of the general formula (II) in an amount of 0.01 to 5% by weight, (ii) air or an oxygen-containing gas, and (iii) combinations thereof;R1OH (II)wherein each R1 independently represents a linear or branched C1-12 alkyl group.展开▼
