Abstract (en)

[origin: FR2782512A1] The mixed oxide composition provides the oxygen necessary for the conversion reaction giving a good selectivity in acrolein. The oxide can be re-generated. The solid oxide composition of the formula (I) :- Mo12BiaFebCocNidSieKfCrgOx (I) a = 0.5 - 5 ; b = 0.1 - 10 ; c = 0.5 - 10 ; d = 0 - 10 ; e = 0 - 15 ; f = 0 - 1 ; g = 0.1 - 2 ; (limits inclusive) and x = amount of oxygen bound to the other elements, dependent on their oxidation states -is used in the preparation of acrolein by oxidation of propylene by the redox reaction :- SOLID (oxidized) + propylene--------------- Solid(reduced) + acrolein (1) An Independent claim is also included for the manufacture of acrolein using the oxide composition.
