Abstract

Density, ϱ and viscosity, η, of binary mixtures of (a) benzyl alcohol + iso-amyl alcohol and (b) benzyl alcohol + isopropyl alcohol, and their pure components, have been measured as functions of concentration and temperature. Theoretical values of sound velocity, U, for the above mixtures are evaluated using Jacobson's relation, based on the free length theory, and that of Schaffs, based on the collision factor theory. The excess volume, V^E, the excess adiabatic compressibility, β^E_s, the excess viscosity, η^E, and the excess molar free energy of activation of flow, G^∗E are found to be negative over the entire range of concentrations and temperatures in both systems, indicating strong interactions.

Predicting physical properties of oxygenated gasoline and diesel range fuels using machine learning
2023, Alexandria Engineering Journal
Understanding the physical properties of distillate petroleum fuels like gasoline and diesel is very critical to ensure the normal operation of internal combustion (IC) engines with regards to processes like spray atomization, heating, evaporation etc. Two of most important physical properties are density and viscosity. Many factors such as molecular structure, molecular weight, temperature etc. effect the physical properties of the fuel. The present work deals with the development of a machine learning model for predicting the density and viscosity of petroleum fuels containing oxygenated chemical classes such as alcohols, esters, ketones and aldehydes. The model was developed using the molecular structure of the compounds expressed in the form of functional groups as inputs. The density and viscosity of 164 pure compounds spanning various chemical families and 14 blends of known compositions was collected from the literature. An artificial neural network model (ANN) for predicting density and viscosity was developed using the neural network tool in Matlab. Each of the ANN model was tested against 15% of the data and the results show that the models were able to successfully predict the density and viscosity of the unseen data points to a good accuracy. A regression coefficient of 0.99 (for density) and 0.98 (for viscosity) was obtained for the test set. The developed models can be used to predict and screen the density and viscosity of real petroleum fuels containing drop in oxygenated bio-fuels.
Statistical measurement and micellar properties of cationic surfactants: Pure and mixed state at different temperature

This article has been withdrawn: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).
This article has been withdrawn as part of the withdrawal of the Proceedings of the International Conference on Emerging Trends in Materials Science, Technology and Engineering (ICMSTE2K21). Subsequent to acceptance of these Proceedings papers by the responsible Guest Editors, Dr S. Sakthivel, Dr S. Karthikeyan and Dr I. A. Palani, several serious concerns arose regarding the integrity and veracity of the conference organisation and peer-review process. After a thorough investigation, the peer-review process was confirmed to fall beneath the high standards expected by Materials Today: Proceedings.
The veracity of the conference also remains subject to serious doubt and therefore the entire Proceedings has been withdrawn in order to correct the scholarly record.
Ultrasonic studies on ternary liquid mixtures of some 1-alkanols with meta methoxy phenol and n hexane at 313 K

The thermo-physical parameters like density (ρ), ultrasonic velocity (U) and viscosity (η) have been experimentally measured for the Ternary Liquid Mixtures of Meta Methoxy Phenol (MMP) in n Hexane with 1 alkanols such as 1 propanol or 1 butanol or 1 pentanol at constant temperature 313 K and fixed frequency of 2 MHz. The thermodynamic and acoustical parameters such as adiabatic compressibility(β), absorption coefficient (α/f²), internal pressure(π_i), cohesive energy(CE), free volume(V_f), free length(L_f), acoustic impedance(z), available volume(V_a), viscous relaxation time, ∆G value, Lenard Jones potential, Degree of intermolecular interaction(χ) and K value were calculated from the experimental data. The various excess properties including excess acoustic impedance(Z^E), excess free length(L_f)^E, excess adiabatic compressibility(β^E), excess free volume(V_f^E), excess ultrasonic velocity (U^E) and excess internal pressure(π_i^E) were also computed from the calculated values. The values of U^E, Z^E, and L_f^E for each mixture have been fitted to the Redlich –Kister polynomial equation. The variation of these parameters with respect to different concentration at constant temperature for the three systems namely MMP+ 1 Propanol+n Hexane, MMP+ 1 Butanol+n Hexane and MMP+ 1 Pentanol+n Hexane have been discussed in the light of molecular interaction. Further, theoretical studies like Van Dael Ideal Mixing Relation, Impedance Dependant Relation, Junjie's and Nomoto's relation are validated with respect to experimental velocities at 313 K for all the different concentrations ranging from 0.001 M to 0.01 M of all the three systems and the Chi-square test for the goodness of fit is applied to check the validity of the theories.

2019, Materials Today: Proceedings
With the help of the measured values ultrasonic velocity (u), viscosity(η) and density (ρ), the excess properties, ultrasonic velocity (U^E), excess acoustic impedance (Z^E), excess intermolecular free length (L^E_f) excess adiabatic compressibility(β^E), excess free volume(V_f^E) and excess internal pressure have been calculated for the ternary liquid mixtures containing 2-Nitroanisole, 1- Pentanol in n-Hexane at various temperatures viz., 303, 308 and 313K at a constant frequency 2 MHz for different concentrations ranges from 0.001M to 0.01M and fitted to the Redlich-Kister polynomial equation. The excess ultrasonic velocity, excess acoustic impedance, excess intermolecular free length, excess adiabatic compressibility, excess free volume and excess internal pressure were plotted against the concentration of the mixture at different temperatures. A good agreement has been found between the experimental and calculated values of the ultrasonic velocity. The strength and the nature of the interactions between like and unlike molecules have been discussed
