Local Compositions and Thermodynamics of Polar/non-polar Mixtures

Thermodynamics, Solvents effects and 1H ,13C NMR Shielding :Theoretical studies of Adamantane

Some of the Adamantane properties were calculated in this study. Chemical shift, free energy ofsolvation, free energy of cavity formation, Henry's law constant, and other properties ofAdamantane in dry phase, three solvents and three temperatures have been calculated with Abinitio method base on density functional theory (DFT) at B3lyp/6-31g, B31yp/6-31g*, B3lyp/6-31+g* and B3lyp/6-31++g** leve...

Separation of Aromatic and Alcoholic Mixtures using Novel MWCNT-Silica Gel Nanocomposite as an Adsorbent in Gas Chromatography

The separations of alcohols with hydrophilic and hydrophobic parts, and the separation of aromatic mixtures, are extremely important processes in gas and petroleum industries. Choosing an adsorbent for performing this separation is the most important part of the process. Silica gel is used as an adsorbent is various techniques such as pressure swing adsorption (PSA) and gas and liquid chromatog...

The Liquid Density of Complex Liquid Mixtures

A second virial coefficient correlation suitable for two different temperatures ranges, (T*)-2£180 and (T*)-2>180, where T* is RT/DHvap is presented. The equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from Ttp to T<su...

Dielectric Study on Polar Binary Mixtures of (Ester-Alcohol) at 298.2 K

Thermodynamic Properties of Polar Substances: Enthalpy of Hydrocarbon- Alcohol Systems

The industrial interest in petroleum compounds has generated large amounts of data for both pure components and mixtures of hydrocarbons. These data and the general similarity in molecular structure of the components have made it possible to develop reasonably precise methods for predicting thermodynamic properties of hydrocarbons over a wide range of conditions. When chemically dissimilar mixt...
