COMPOSTOS AROMATICOS PDF

Micage However, the glycerol has presented as the most promising solvent for aromatics extraction. USA6 O primeiro trabalho completo surgiu emusando espectrometria de massas 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. The separation of these components is realized, generally, the liquid-liquid extraction process. These are commonly derived from reformed naphtha, which are in multicomponent mixtures with aliphatic hydrocarbons. B34 The results were considered satisfactory, noting that the NRTL was the model that presented minor deviations in compositions. In this process, the sulfolane is the most widely used solvent.

B38 In this process, the sulfolane is the most widely used solvent. Aromatic nitration is one of the most relevant class of reactions in organic chemistry. Navarro, Myriam Lorena Melgarejo Published: Thus, in this study were also studied the density and viscosity of solvent extractors aromatic.

B B32 Reis, Maria Ines Jacques dos Published: Aromatic hydrocarbons are chemical compounds of great interest aromatico the petrochemical industry.

Estes estudos levaram a resultados inesperados. However, aromatixos published results do not seem to converge to an unique mechanism. The results were considered satisfactory, noting that the NRTL was the model that presented minor deviations in compositions. How to cite this article. With this data, it can be concluded that all the solvents studied have a good capacity for toluene extraction from mixtures with decane. The separation of these components is realized, generally, the liquid-liquid extraction process.

The physical properties also of great importance in the understanding of the behavior and interactions that occur in liquid mixtures. It has been intensively studied by both experimental, including works in the comopstos as well as in the gas phase, and theoretical procedures.

II Este trabalho confirmou, de forma geral, os resultados cojpostos. 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.

Estes resultados podem ser interpretados em termos da exotermicidade do processo. Desta forma, reatividade e seletividade posicional seriam determinadas em etapas distintas.
