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 ...
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.
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 ...
Vanadium(II) oxide is the inorganic compound with the idealized formula VO. It is one of the several binary vanadium oxides. It adopts a distorted NaCl structure and contains weak V−V metal to metal bonds. VO is a semiconductor owing to delocalisation of electrons in the t 2g orbitals.
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.
Vanadium(III) oxide is the inorganic compound with the formula V 2 O 3. It is a black solid prepared by reduction of V 2 O 5 with hydrogen or carbon monoxide. [3] [4] It is a basic oxide dissolving in acids to give solutions of vanadium (III) complexes. [4] V 2 O 3 has the corundum structure. [4]
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.
