Vanadium pentoxide | V2O5 - PubChem

Vanadium pentoxide may be shipped domestically via air, rail, road, or water. Small spills of vanadium pentoxide may be collected and placed in clean, dry containers for later disposal (liquid solutions are taken up with sand or noncombustible absorbent). Large spills on land should be contained in excavated pits or other holding areas.

Vanadium(V)oxide - Wikipedia

Vanadium(V)oxide kan gereduceerd worden door oxaalzuur, koolstofmonoxide of zwaveldioxide tot vanadium(IV)oxide. De kleur van de oplossing verandert hierbij van oranje naar diepblauw. Verdere reductie met waterstofgas of een overmaat koolstofmonoxide leidt tot een complex mengsel van oxiden, zoals V 4 O 7 en V 5 O 9 , wat verder reageert tot het zwarte vanadium(III)oxide .

3.5.4 Carcinogenicity. Vanadium pentoxide is classified as possibly carcinogenic to humans (Group 2B) by the IARC. There are no data on the carcinogenic effects of vanadium compounds in humans. Furthermore, certain vanadium compounds have been proposed as chemotherapeutics [224].

Vanadium - Wikipedia

Vanadium compounds are used extensively as catalysts; Vanadium pentoxide V 2 O 5, is used as a catalyst in manufacturing sulfuric acid by the contact process In this process sulfur dioxide (SO 2) is oxidized to the trioxide (SO 3): In this redox reaction, sulfur is oxidized from +4 to +6, and vanadium is reduced from +5 to +4:

Vanadium(IV) oxide - Wikipedia

Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO 2.It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO] 2+ and in alkali to give the brown [V 4 O 9] 2− ion, or at high pH [VO 4] 4−. VO 2 has a phase transition very close to room temperature (~66 °C).

Vanadium Pentoxide V2O5 for Catalyst

1.Vanadium pentoxide which is mainly used as the catalyst for a variety of gas-phase oxidation processes, particularly the conversion of sulfur dioxide to sulfur trioxide during the manufacture of sulfuric acid. The most frequently used Vanadium Pentoxide Catalyst contains 4–6% vanadium as vanadium pentoxide on a silica base.

Vanadium(III) acetylacetonate - Wikipedia
