C 4 H 10 + 4 O 2 → C 2 H 2 (CO) 2 O + 8 H 2 O. Maleic anhydride is used for the production of polyester resins and alkyd resins. [15] Phthalic anhydride is produced similarly by V 2 O 5-catalysed oxidation of ortho-xylene or naphthalene at 350–400 °C. The equation for the vanadium oxide-catalysed oxidation of o-xylene to phthalic anhydride:
Phases with the general formula V n O 2n+1 exist between V 2 O 5 and VO 2. Examples of these phases include V 3 O 7, V 4 O 9 and V 6 O 13. [1] Phases with the general formula V n O 2n−1 exist between VO 2 and V 2 O 3. [1] Called Magnéli phases for Arne Magnéli, [2] they are examples of crystallographic shear compounds based on the rutile ...
4, is the principal species present at pH 12–14. Similar in size and charge to phosphorus(V), vanadium(V) also parallels its chemistry and crystallography. Orthovanadate V O 3− 4 is used in protein crystallography [5] to study the biochemistry of phosphate. [6] Beside that, this anion also has been shown to interact with activity of some ...
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

The contact process is a method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, because it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5) has since been preferred.
Ammonium metavanadate is the inorganic compound with the formula NH 4 VO 3. It is a white salt, although samples are often yellow owing to impurities of V 2 O 5. It is an important intermediate in the purification of vanadium. [2]
333t an undergraduate chemistry student could understand, and a high school student could get the gist of. Make the section briefer; currently this section is about as long as the "uses" section. Considering the huge importance of the uses of V2O5, that makes it unbalanced.
In chemical nomenclature when vanadate forms part of the name, it indicates that the compound contains an anion with a central vanadium atom, e.g. ammonium hexafluorovanadate is a common name for the compound [NH 4] 3 [VF 6] with the IUPAC name of ammonium hexafluoridovanadate(III).
