“…As shown in Figure 3, a plot of log k, v. T -' indicates that the Arrhenius relationship is followed. The data are well correlated by the expression: among the values 2.71 m3/kmol -s by Donaldson and Nguyen (1980), 2.85 m'/kmol s by Barth et al (1981), 2.9 m'/kmol -s by Blauwhoff et al (1984), and 3.6 m3/kmol s from the present investigation. These values are all significantly lower compared to the 16.8 m'/kmol .…”

“…For aqueous TEA solutions at 298 K, there is a good agreement between the results of various authors and techniques (Donaldson and Nguyen, 1980;Barth et al, 1981;Blauwhoff et al, 1984). The rate constant at 298 K reported by Crooks and Donnellan (1990) is somewhat lower than the value reported by the previous authors.…”

The reaction of CO, with TEA, DMMEA, and DEMEA has been studied at 293, 303, 318 and 333 K. All the kinetic experiments were carried out in a stirred cell reactor operated with a flat, smooth and horizontal gas-liquid interface. A numerical method, which describes mass transfer accompanied by reversible chemical reactions, has been applied to infer rate constants from the experimental data. It is argued that the contribution of the CO, reaction with OH-to the observed reaction rate may have been overestimated in most literature on tertiary amine kinetics as serious depletion of OH-toward the gas-liquid interface usually occurs.For all the amines studied, the reaction order in amine was found to be about one for each temperature investigated. This is in good agreement with the base catalysis mechanism proposed by Donaldson and Nguyen (1980). All kinetic data could be summarized reasonably well in one BrBnsted relationship. R. J. Littel

“…Kinetic parameters are optimized to reduce deviation between the model and experimental data. This kind of models is necessary when spectrophotometric detection is used to follow the reaction (Barth et al, 1981(Barth et al, , 1983(Barth et al, , 1984(Barth et al, , 1986 or if operating conditions like CO 2 loading is not compatible with an analytical solution of the model (Conway et al, , 2012McCann et al, 2009McCann et al, , 2011Wang et al, 2011;Xiang et al, 2012).…”

Re´sume´-Cine´tique du dioxyde de carbone avec les amines -I. É tude par stopped-flow en solution aqueuse. Une revue -Il est possible de trouver de nombreuses informations sur la cine´tique de re´action amine-CO 2 dans la litte´rature. Toutefois, comme il existe plusieurs techniques expe´rimentales et plusieurs me´canismes re´actionnels possibles, on observe parfois une grande dispersion des re´sultats expe´rimentaux avec diverses interpre´tations. Dans cet article, une me´thode qui permet de comparer les constantes cine´tiques obtenues par diffe´rents auteurs est propose´e. D'abord nous pre´sentons les diffe´rentes techniques expe´rimentales et justifions de comparer les donne´es obtenues par la technique d'e´coulement a`flux bloque´. Ensuite nous repre´sentons les donne´es cine´tiques des diffe´rentes amines e´tudie´es dans la litte´rature a`partir d'une de´pendance en loi puissance en fonction de la concentration. Cette repre´sentation illustre certaines relations structure-proprie´te´et permet de confronter les donne´es expe´rimentales aux diffe´rents me´canismes propose´s. Les avantages et limites de chaque me´canisme sont discute´s. Finalement nous justifions l'utilisation d'un mode`le termole´culaire pour comparer les donne´es obtenues par diffe´rents auteurs. Ce mode`le conduit a`l'observation d'un phe´nome`ne de compensation qui est un argument en faveur du me´canisme correspondant.Abstract -Kinetics of Carbon Dioxide with Amines. I. Stopped-Flow Studies in Aqueous Solutions. A Review -It is possible to find plenty of information about kinetics of reaction between amine and carbone dioxide in the literature. However, there are several experimental techniques and several possible mechanisms which lead to observe sometimes high dispersion of experimental results with various interpretations. A method which enables to compare kinetic constant got by different authors is proposed in this work. First, we present experimental techniques and justify comparison of data obtained by stopped-flow technique. Then, we plot kinetic data for all amines studied in the literature by a power law dependency with the concentration. This representation illustrates some structureactivity relationships and enables to confront experimental results with the different mechanisms. Advantages and limits of each mechanism are discussed. Finally, we justify the choice of the termolecular model to compare data got by different authors. This model leads to a compensation effect which is an argument in favour of this mechanism.
