Estimination of Ternary System (Water + Acetic acid + Cyclohexanol) under Ultrasonic Wave using GMDH-type Neural Network

In chemical industries, liquid extraction plays an important role as a separation process. The design and evaluation of industrial units for separation processes require reliable phase equilibrium data of the different mixtures involved in a given process. Especially, ternary liquid + liquid equilibrium (LLE) data are essential for a proper understanding of the solvent extraction [۱, ۲].Ultrasonic refers to any study or application of sound waves that are higher frequency than the human audible range. Ultrasonic waves consist of frequencies greater than ۲۰ KHz and exist in excess of ۲۵ MHz. Effect of ultra sonic wave on LLE data of several ternary systems have been determined before and reported [۳].The new approach in this paper is using GMDH type-neural network in prediction of LLE data under ultrasonic wave (۲۰ KHz) for the ternary system of (water + acetic acid + cyclohexanol). The predicted data by the proposed model was then compared with the experimental data.
