Resume

La décarboxylation de l'acide oxaloacétique en acide pyruvique a été étudiée en présence de montmorillonite saturée en cations différents et des mêmes cations à l'état libre (non incorporés). L'action catalytique dépend de la nature du cation, cést-à-dire de sa facilité à former des complexes avec l'acide oxaloacétique. Le réseau argileux intervient dans la catalyse essentiellement par les atomes d'aluminium (ou de fer) situés sur les bords des feuillets argileux. Il joue le rôle d'un métalloenzyme biologique. Le calcul des énergies d'activation pour les différents systèmes met bien en évidence l'activité catalytique de l'argile. En présence du phyllosilicate, la réaction a lieu avec un bon rendement jusqu'à une température de 60°C.

Abstract

Abstract

Oxaloacetic acid decarboxylation into pyruvic acid and carbon dioxide was studied in the presence of montmorillonite saturated with different cations, and in the presence of the same cations in their free state (non-incorporated). The catalytic effect is a function of the nature of the cation, i.e. its ability to form chelate complexes with oxaloacetic acid. The clay mineral structure plays an important role in the decomposition of the oxalo-acetic acid molecule, the aluminium atoms at the edges of the crystals being the active sites. Thus the clay mineral acts as a metalloenzyme. Activation energy computations for the different systems illustrate the influence of the clay structure in this catalytic process. In the presence of montmorillonite, the reaction yield was high up to 60°C.
