PROCESS FOR THE PRODUCTION OF ACRYLIC ACID FROM ACROLEIN BY REDOX REACTION AND THE USE OF A SOLID COMPOSITION OF MIXED OXIDES AS A REDOX SYSTEM IN SUCH A REACTION

摘要

The present invention relates to the use of a solid composition of mixed oxides of formula (I): (CF DRAWING IN BOPI) 2 = a = 14; 0.1 = b = 6; 0 = c = 12; 0 = d = 6: 0 = e = l5; x is the amount of oxygen bound to other elements and depends on their oxidation states, in the manufacture of acrylic acid by oxidation of acrolein, said solid composition reacting with acrolein according to the redox reaction (1) : Oxidized SOLID + ACROLEIN - Reduced SOLID + ACRYLIC ACID (1)
