FUGACITY COEFFICIENTS IN BINARY MIXTURES CONTAINING ACETIC ACID

Calculation and Prediction of Fugacity and Activity Coefficients in Binary Mixtures, using a Self-Regulated Fretwidth Harmony Search Algorithm*

Abstract This research article proposes the use of a novel variant of the HS algorithm (harmony search), i.e. SFHS (self-regulated fret width harmony search algorithm), for calculating and predicting fugacity and activity coefficients in binary mixtures. Parameter selection was carried out based on preliminary results with different standard test functions. Different previously reported systems...

Transport coefficients of binary and ternary mixtures of DCMIX project

We present the thermodiffusion, molecular diffusion and Soret coefficients of several binary and ternary mixtures of DCMIX project. All measurements were carried out at 25oC and two experimental techniques have been used such as the thermogravitational column technique (TGC) and the Sliding symmetric Tubes technique (SST). In addition the thermophysical properties of analysed mixtures have been...

Group Contribution Method for Predicting the Phase Behavior of Binary Mixtures Containing Carbon Dioxide

Ultrasonic Behaviour of Binary Mixtures Containing Stearates and Acetone

The ultrasonic velocity measurements along with density and viscosity in the binary mixtures of zinc stearate acetone and calcium stearate acetone at 303 K are studied. It is used to evaluate the different thermo acoustical parameters along with the excess properties. The experimentally determined velocities have been compared with theoretically estimated values obtained using different empiric...

Physicochemical Parameters Study of Chitosan-starch- Glutaric Acid in Acetic Acid-water Mixtures

Knowledge of the physicochemical parameters values produced by the utilization of the polymer blends is important because of the effect that it has on the operational cost of several stages of the industrial process Chitosan/starch solutions of different variable concentrations from (90/10 to10/90) are prepared in dilute acetic acid solution (1%). Glutaric acid solution concentration is 1% fixe...
