Emulsions are thermodynamically unstable systems and are used in various types of industrial applications such as oil recovery, resin preparation, among many other applications. In the present work are discussed and shown data of the new emulsion system formed by components Chitosan/SDS/Hexane. The preparation and characterization of this emulsion were used the techniques of tensiometry, turbidity and flow time. The methodology requires that the participation of the paraffinic compounds as hexane, the biopolymer chitosan and the anionic surfactant Sodium Dodecylsulfate (SDS) with favorable intermolecular interactions between these three components. The results showed that a larger amount of chitosan about 85% (v/v) in the system causes of an increase in the value of surface tension, reaching 39.62 mN/m. However, high amounts of SDS about 70% (v/v) there is an increase in the turbidity values of the emulsions, with a maximum value of 110.8 NTU.

The paraffinic compounds are important to new investigation on the properties physics and its correlation with theoric dates, because in literature no is completely clarified. However, there are some studies on the formalism for developing asymptotic behavior correlation for homologous series paraffin compounds. In this work is show that the effect of parameters theoric obtained by molecular modeling can be correlated with experimental dates. To paraffins as pure, for example, n-hexane, C6H14, MW 158 g/mol, is composed of two groups CH3 and four groups CH2 and its can depending of structure molecular ramification to predict what your dependency with thermodynamics data. Therefore, the molecular modeling of paraffinic compounds uses a methodology that looks for data correlated with the structure of the molecule complemented with experimental data. The objective this study is correlated this molecular data with some thermodynamics data as enthalpy of formation and other parameters.
