| titleOfInvention | Process for preparing molybdenum and/or tungsten oxides catalysts and other metals oxides catalysts |
| abstract | PRECISION OF DISCLOSURE: The invention relates to a process for the preparation of catalysts comprising an active phase corresponding to the general mule: Aa Moc Wd Bb Ox in which: A represents at least one metal chosen from the group comprising cobalt, nickel, manganese, lead; B represents at least one metal chosen from the group comprising iron, bismuth, chromium, thallium; a representing the sum of the indices assigned to each of the metals A, is greater than 0 and less or equal to about 12; c and d are each greater than or equal 0 and less than or equal to 12, their sum c + d being equal at around 12; b representing the sum of the indices affected to each of the metals B, is greater than 0 and less than or equal to about 1.5 [(c + d) -a]; and x satisfies the valences, process of the type according to which, in a first step, mixture in aqueous phase of the salts of metals entering the composition of the active phase, molybdenum and / or tungsten being in the form of ammonium salts and at least one of the metals A and B being in the form of a nitrate or a chloride, in a second step, the paste obtained is dried and in a third step, at least one calculation is carried out nation of the solid obtained possibly deposited on a support, process characterized in that in the first step, success We add to a first aqueous solution holding the ammonium salts of molybdenum and tungsten in quantity making it possible to reach the values c and d, of the am-moniacal until a pH between about 6 and about 8; we add to the resulting solution simultaneously, on the one hand, a second aqueous solution containing the salts of A and B in quantities to reach the values a and b and, on the other hand, ammonia so set the pH to a value between about 6 and about 8; then in that we filter the solution obtained to obtain said dough. The catalysts thus obtained are in particular usable for the synthesis of .alpha .-. beta aldehydes. unsaturated by oxidation of olefin in the gas phase. |
