Savage, Auteur ; Xiuyang Lu, Auteur Année de publication : 2010 Article en page(s) : pp. 10467–10471 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Hydrothermal--Decarboxylation--Pentafluorobenzoic--Acid--Quinolinic--Acid Résumé : We report herein the first kinetics studies of hydrothermal decarboxylation of a fully halogenated benzoic acid and a heterocyclic aromatic diacid. Decarboxylation was the only reaction path observed, and there was no evidence of dehalogenation. Experiments at different initial reactant concentrations and different batch holding times revealed that both compounds exhibited first-order kinetics. Experiments at different temperatures showed that the first-order rate constants displayed Arrhenius behavior with activation energies of 157 kJ mol−1 for pentafluorobenzoic acid decarboxylation and 141 kJ mol−1 for quinolinic acid decarboxylation.
