B1. USA79 However, the glycerol has presented as the most promising solvent for aromatics extraction. Mesquita, Francisca Maria Rodrigues.

These are commonly derived from reformed naphtha, which are in multicomponent mixtures with aliphatic hydrocarbons. The composition data of tie-lines, obtained experimentally, were used to calculate the selectivity parameter and the distribution coefficient. Acta, 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.

Estes estudos levaram a resultados inesperados. Services on Demand Journal. Estes resultados podem ser interpretados em termos da exotermicidade do processo. Este trabalho confirmou, de forma geral, os resultados anteriores. Electrophilic substitution and electron transfer, in an exclusive way, are both proposed as the main mechanism for the reaction. Considerando que o mesitileno tenha constante de velocidade cerca de 40 vezes maior do que a constante de velocidade do benzeno, conforme a Tabela 2.

We review these proposals and discuss the most recent findings. Navarro, Fabiana Maria Salvador Published: With this data, it can be concluded that all 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. Aromatic nitration is one of the most relevant class of reactions in organic chemistry.

The separation of these components is realized, generally, the liquid-liquid extraction pr Navarro, Myriam Lorena Melgarejo Published: Isto faz com que a constante de velocidade k -1 seja muito maior do que aromatifos r [ArH]. It has been intensively studied by both experimental, including works in the condensed as well as in the gas phase, and theoretical procedures. Cornejo Ponce, Lorena Published: Desta forma, reatividade e seletividade posicional seriam determinadas em etapas distintas.

Aromayicos, best represented the LLE data for the systems studied. 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 ] in extracting aromatic mixtures with aliphatic.

B38 The separation of these components is realized, generally, the liquid-liquid extraction process. Reis, Maria Ines Jacques dos Published: How to cite this article.

II Thus, in this study were also studied the arokaticos and viscosity of solvent extractors aromatic. The experimental methodology for the determination of LLE data was initially validated by reproducing the literature, and the results showed good agreement between these data.
