Full textA modified form of the Flory-Huggins theory was developed for liquid-liquid equilibrium in binary aqueous systems of nonelectrolytes whose closed-loop phase diagrams contain both upper and lower consolute temperature points. The modification involved the assumption of an adjustable molecular size parameter $ chi sb{12}$. Calculations were performed for 15 aqueous binary systems. The models correlated the liquid-liquid equilibrium data accurately.
Liquid-liquid equilibrium in aqueous biphasic salt systems was modelled using an expression for the excess Gibbs energy of the solution. The expression is based on modified forms of the Mean Spherical Approximation, the Bromley equation, and the Flory-Huggins theory. The model requires 3 and 5 adjustable parameters for tenary and quaternary systems, respectively. The model accurately correlated vapor- and liquid-liquid equilibrium data for 8 ternary and 3 quaternary aqueous biphasic salt systems.

Full textA catálise heterogénea é usada em 80% dos processos industriais catalíticos porque envolve uma fácil separação dos reagentes e produtos da reacção. A catálise homogénea, por sua vez, apresenta a grande vantagem de se poder usar diversos modelos capazes de descrever e prever as propriedades da mistura reaccional, embora apresente uma difícil separação e recuperação dos compostos envolvidos. A catálise bifásica consegue reunir as vantagens de ambos os tipos de catálise homogénea e heterogénea. Este método consiste em utilizar dois solventes imiscíveis a temperatura ambiente, onde o catalisador encontrase imobilizado em uma fase e os reagentes na outra. Através de um aumento da temperatura formase uma única fase onde ocorre a reacção. Ao arrefecer, as fases separamse permitindo a separação dos produtos e do catalizador, que pode ser reutilizado. Em particular, desde a primeira publicação, em 1994, que Horváth e Rábai demonstraram que os sistemas bifásicos fluorados podem ser altamente vantajosos em uma grande variedade de reacções químicas orgânicas, usando perfluorocarbonetos como meio de reacção. Este trabalho tem como principal objectivo o estudo do equilíbrio líquidolíquido de sete novos sistemas binários contendo compostos fluorados e solventes orgânicos, contribuindo com novos dados experimentais e teste de modelos nestes sistemas. O método utilizado foi a turbidimetria, usando um método dinâmico de detecção visual. Foram preparadas várias ampolas com composições diferentes para cada sistema. A mistura foi aquecida em um banho termostatizado a uma temperatura onde apenas uma fase era observada. Ao arrefecer lentamente essa mistura, observouse a separação das fases e a respectiva temperatura foi registada. Os resultados obtidos foram correlacionados coma dois modelos que usam diferentes abordagens. A equação de estado softSAFT foi utilizada para correlacionar os dados experimentais de forma satisfatória. O COSMORS, modelo baseado em cálculos de química quântica foi utilizado para prever o comportamento das solubilidades mútuas dos compostos envolvidos, tendose verificado uma ferramenta útil no caso de sistemas envolvendo tolueno e acetonitrilo.
Due to the easy separation of the reactants from reaction products, almost 80% of industrial catalytic reactions use heterogeneous catalysts. The homogeneous catalysis has the great advantage that models can be used to describe and predict the properties of the species involved in the catalytic reaction, but its main limitation is the separation and recovery of the products from the catalyst. The biphasic catalysis gather the advantages of both types of catalysis. This method consists on using two solvents which are immiscible at room temperature maintaining the catalytic system immobilized in one phase while the reactants and products remain in the other phase. By rising the temperature, the mixture becomes completely miscible allowing reactions to proceed homogeneously. On cooling, the phases separate allowing the facile catalyst/product separation. Since the first publication in 1994, by Horváth and Rábai, fluorous biphasic systems (FBS) have shown to have advantages in a wide variety of chemical organic reactions including catalytic reactions, using perfluorocarbons (PFC) as reaction media. The aim of this work is the study of liquidliquid equilibrium (LLE) of seven original binary systems containing highly fluorinated compounds and an organic solvent. This work contributes with new experimental LLE data of fluorous biphasic systems, measured using turbidimetry with naked eye visual detection. Several ampoules were prepared with different compositions for each system. The mixture was heated in a thermostatic bath until just one phase was observed. On slowly cooling, the phase separation temperature was registered. The obtained results were modeled using two different approaches. The softSAFT equation of state was used successfully to correlate the experimental data. COSMORS, a predictive method based on unimolecular quantum chemical calculations for individual molecules, was used to predict the phase behavior of the involved compounds and revealed to be a special useful tool in the case of toluene and acetonitrile mixtures.

Full textIn the process of purification of biodiesel is of extreme importance washing methyl or ethyl ester rich- phase, since in conventional processes there is a great amount of water. During the washing is extracted primarily excess alcohol. Composition data for the washing process of biodiesel is still scarce in the literature and the study of liquid-liquid equilibrium provides the means to develop equipment and to optimize the extraction processes. Thus the main goal of this work is to determine equilibrium data for three different ternary systems: water - methanol - soybean biodiesel; corn biodiesel â methanol â water; methanol - coconut biodiesel - water at 20 Â C and 40 Â C. The experiments were carried out in equilibrium cells where the temperature was kept constant by thermostat control. The experimental determination was made by the method of densimetry. The consistency of data obtained for the tie lines was verified by correlations. It was verified by the ternary graphs, little influence of temperature on the systems studied. The equilibrium data were correlated liquid-liquid models for the activity coefficient NRTL, UNIQUAC and UNIFAC and proved quite satisfactory.
No processo de purificaÃÃo do biodiesel, a lavagem da fase rica em metil ou etil Ãster à de extrema importÃncia, visto que nos processos convencionais hà um grande gasto de Ãgua. Durante a lavagem à extraÃdo principalmente Ãlcool em excesso. Dados de composiÃÃes para a lavagem de biodiesel ainda sÃo escassos na literatura e o estudo do equilÃbrio lÃquido-lÃquido pode fornecer meios para o desenvolvimento de equipamentos e otimizaÃÃo dos processos de extraÃÃo. Dessa forma, o principal objetivo dessa dissertaÃÃo foi determinar dados de equilÃbrio lÃquido- lÃquido para os sistemas ternÃrios contendo biodiesel de soja + metanol + Ãgua, biodiesel de milho + metanol e Ãgua e biodiesel de coco + metanol + Ãgua, a 20 ÂC e 40 ÂC. Os experimentos foram feitos em cÃlulas de equilÃbrio mantendo a temperatura constante. A determinaÃÃo experimental das misturas ternÃrias foi feita pelos mÃtodos de titulaÃÃo e densimetria. A consistÃncia dos dados das linhas de amarraÃÃo foi verificada pelas correlaÃÃes de Othmer-Tobias e Hand. Verificou-se por meio de grÃficos ternÃrios, pouca influÃncia da temperatura sobre os sistemas estudados. Os dados de equilÃbrio lÃquido-lÃquido foram correlacionados pelos modelos para coeficiente de atividade NRTL, UNIQUAC e UNIFAC e mostraram-se bastante satisfatÃrios.

Full textOur work focuses on solutal melting, which occurs when two metals are brought into contact at a temperature between their respective melting temperatures. The solid/liquid interface is initially far from equilibrium, and the kinetics governing its return to equilibrium appear to challenge the models commonly used to describe solidification and melting. To advance our understanding of the process, we approached the problem from three complementary angles. First, we conducted in-situ experiments on the solutal melting of the Au-Ag system using X-ray tomography. Critical analysis of the results appears to indicate that the solid-liquid interface remains out of equilibrium during solutal melting, with the unexpected persistence of concentration gradients at the end of the experiments. Second, in an effort to better understand the experiments, we developed a model based on the thermodynamics of irreversible processes applied to the exchange of chemical species across a sharp solid/liquid interface. Parametrization of interfacial transfer coefficients enables the model to qualitatively reproduce the behaviors observed in the experiments. Finally, we sought to justify the kinetic parameters of the thermodynamic model using molecular dynamics (MD) in the Cu-Ni system. We thus demonstrated that the interfacial coefficients depend on the concentrations at the interface, consistent with the parametrization of the thermodynamic model
