Estes resultados podem ser interpretados em termos da exotermicidade do processo.

B Cuelbas, Claudio Jose Published: Given the above, this study main aims to determine liquid-liquid equilibrium data LLE to study the ability of solvents [diethylene glycol DEGtriethylene glycol TEGglycerol and 2-hydroxyethyl amine format 2-HEAF aeomaticos in extracting aromatic mixtures with aliphatic. Navarro, Myriam Lorena Melgarejo Published: However, the glycerol has presented as the most promising solvent for aromatics extraction.

Isto faz com que a constante de velocidade k -1 seja muito maior do que k r [ArH]. O primeiro trabalho completo surgiu emusando espectrometria de massas However, this has some disadvantages such as high cost. The separation of these components is realized, generally, the liquid-liquid extraction aromayicos.


These are commonly derived from reformed naphtha, which are in multicomponent mixtures with aliphatic hydrocarbons. IIccompostos For this reason, many studies are developed by the academic community in order to propose alternative solvents to replace the exclusive use of sulfolane by compounds that are important features like good selectivity, easy recoverability and low costs.

Este trabalho foi iniciado durante o curso de Mestrado de S. Thus, best represented the LLE data for the systems studied.

With this data, it can be concluded that arommaticos the solvents studied have a good capacity for toluene extraction from mixtures with decane. Aromatic hydrocarbons are chemical compounds of great interest in the petrochemical industry.

Electrophilic substitution and electron transfer, in an exclusive way, are both proposed as the main mechanism for the reaction. Mesquita, Francisca Maria Rodrigues.

Services on Demand Journal. The separation of these components is realized, generally, the liquid-liquid extraction pr Estes estudos levaram a resultados inesperados. The results were considered satisfactory, noting that the NRTL was the model that presented minor deviations in compositions. B34 Reis, Maria Ines Jacques dos Published: B1.

Aromatic nitration is one of the most relevant class of reactions in organic chemistry. Considerando que o mesitileno tenha constante de velocidade cerca de 40 vezes maior do que a constante de velocidade do benzeno, wromaticos a Tabela 2.

Este trabalho confirmou, de forma geral, os resultados anteriores. Thus, in this study were also studied the density and viscosity of solvent extractors aromatic. The composition data of tie-lines, obtained experimentally, were used to calculate the selectivity parameter and the distribution coefficient. USA6 The experimental methodology for aromsticos determination of LLE data was initially validated by reproducing the literature, and the results showed good agreement between these data.
