    Abstract: Višemetalni oksid opšte formule (I): Aga1bMbV2Ox * c H2O, u kojoj M označava metal odabran iz grupe koja se sastoji od Li, Na, K, Rb, Cs, Tl, Mg, Ca, Sr, Ba, Cu, Zn, Cd, Pb, Cr, Au, Al, Fe, Co, Ni i/ili Mo, a iznosi od 0,3 do 1,9 i b iznosi od 0 do 0,5, uz uslov da je razlika (a-b) ≥ 0,1 i c iznosi od 0 do 20 i x je broj koji je odredjen valencom i frekvencom elemenata različitih od kiseonika u formuli I. Ovaj višemetalni oksid ima kristalnu strukturu koja daje dijagram difrakcije X-zraka praha koji pokazuje refleksije pri rastojanjima prostorne rešetke d od 15,23В±0,6, 12,16В±0,4, 10,68В±0,3, 3,41В±0,04, 3,09В±0,04, 3,02В±0,04, 2,36В±0,04 i 1,80В±0,04 Г…. Ovaj pronalazak se takodje odnosi na prekatalizatore i katalizatore za parcijalnu oksidaciju aromatičnih ugljovodonika.[Polymetal oxide of general formula (I): Aga-bMbV2Ox * c H2O, whereby M is a metal selected from the group of Li, Na, K, Rb, Cs, Tl, Mg, Ca, Sr, Ba, Cu, Zn, Cd, Pb, Cr, Au, Al, Fe, Co, Ni and/or Mo, a has a value of 0.3-1.9 and, b a value of 0-0.5 with the proviso that the difference (a-b)≥0.1, c has a value of 0-20 und x is a number that is determined by the valence and frequency of elements different from oxygen in formula (I). The polymetal oxide has a crystalline structure that results in a powder x-ray diagram with diffraction reflexes for lattice differences of d 15.23 Вµ 0.6, 12.16 Вµ 0.4, 10.68 Вµ 0.3, 3.41 Вµ 0.4, 3.09 Вµ 0.4, 3.02 Вµ 0.4, 2.36 Вµ 0,4 and 1.80 Вµ 0.4 Г…. The invention also relates to precatalysts and catalysts for the partial oxidation of aromatic hydrocarbons.
