Abstract[English]
is Bi, Sb, or a mixture thereof, a is 1.0; b is 0.01 to 0.5; c is 0.005 to 0.2; and x is at least the number of oxygen atoms necessary to render the catalyst electrically neutral. The catalyst 5 has a powder X-ray diffraction (PXRD) pattern including at least five peaks at 2θ values chosen from 7.8 ± 0.2°, 8.9 ± 0.2°, 12.7° ± 0.2°, 22.1 ± 0.2°, 23.3 ± 0.2°, 25.7° ± 0.2°, 27.2° ± 0.2°, 28.0 ± 0.2°, 29.1 ± 0.2°, and 39.0° ± 0.2°, wherein the PXRD pattern is obtained using Cu Kα radiation. The catalyst is essentially free of tantalum and niobium.[French]
est Bi, Sb, ou un mélange de ceux-ci, a est 1,0 ; b est de 0,01 à 0,5 ; c est de 0,005 à 0,2 ; et x est au moins le nombre d'atomes d'oxygène nécessaires pour rendre le catalyseur électriquement neutre. Le catalyseur 5 a un diagramme de diffraction des rayons X sur poudre (PXRD) comprenant au moins cinq pics à des valeurs 2theta choisies parmi 7,8 ± 0,2°, 8,9 ± 0,2°, 12,7° ± 0,2°, 22,1 ± 0,2°, 23,3 ± 0,2°, 25,7° ± 0,2°, 27,2° ± 0,2°, 28,0 ± 0,2°, 29,1 ± 0,2° et 39,0° ± 0,2°, le diagramm PXRD étant obtenu à l'aide d'un rayonnement Cu Kalpha. Le catalyseur est essentiellement exempt de tantale et de niobium.
