Determination of Viscosity in Ethanol and HFA 134A Mixtures
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Loughborough University Institutional Repository Respiratory Drug Delivery 2018 – Johnson et al. Determination of Viscosity in Ethanol and HFA 134a Mixtures Rob Johnson,1 Daniel I. Lewis,1 Paul M. Young,1 Henk K. Versteeg,2 and Graham Hargrave2 1Oz-UK Limited, Chippenham, Wiltshire UK 2Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, Loughborough, UK KEYWORDS: binary mixtures, transient aerodynamic atomization model, metered dose inhaler, propellant INTRODUCTION Knowledge of formulation liquid properties is beneficial when modelling internal transient flows of pMDI HFA 134a and ethanol binary mixtures during atomization [1, 2]. Non-linear expressions are available that correlate saturated vapor pressure, density and surface tension to HFA 134a-ethanol composition [3, 4]. In this study, experimentally determined dynamic viscosity is presented for ethanol-HFA 134a mixtures at 20.4 ± 1.2°C. MATERIALS AND METHODS Viscosity can be described as a fluid’s resistance to shear strain when submitted to a shear stress. For a sphere travelling within a closed capillary containing a liquid, the dynamic viscosity, µ, of the liquid is given by Equation 1 where K is the viscometer constant; rs and rL are the densities of the sphere and liquid respectively; and t is the time of travel of the sphere between two fixed graduation lines. Equation 1 is valid for non-turbulent flow where the sphere is travelling at terminal velocity. To determine the viscosity of HFA 134a (Mexichem Fluor, Runcorn, UK), absolute ethanol (Fisher Scientific, Loughborough, UK) and mixtures, formulations were packaged within a Comes DM density measuring device with a 90 mL Pyrex inner tube (DH Industries Limited, Laindon, UK). -
Structural Analysis of Water and Alcohol Solutions
Structural analysis of water and alcohol solutions A thesis submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Master of Science in the Department of Materials Science of the College of Engineering and Applied Science by Kelly J. Cross B.S. Purdue University May 2007 Committee Chair: Dale W. Schaefer, Ph.D. Abstract Water-alcohol solutions have been extensively studied to correlate molecular structure to thermodynamic properties, which are known to deviate strongly from ideality. This project offers an analysis of cluster formation in ethanol-water binary solutions and an approach to identify distinctive structures within water and alcohol (W-A) solutions. Thermodynamic properties (such as enthalpy) and hydrogen bond strength can provide physical evidence of clustering within the solution. The heat of mixing was observed as a function of concentration. The concentration dependence of hydrogen bonding strength was analyzed through Infrared spectroscopy. Molecular aggregation in solution was explored experimentally with light scattering. Some of the results were consistent with published data and some results did not support data in the current literature. The calorimetry data were consistent with the published data showing a minimum at ~20 mol%. In the water rich region, we assume the hydrogen-bonded water clusters isolate individual ethanol molecules. The frequency shift observed with IR spectroscopy shows that the C-O bond strength increases with increasing ethanol concentration. Similar to the observations of D’Angelo, the frequency shift of the C-O and C-H stretching is concentration-dependent and is attributed to the transfer of electron density from the carbon of the methyl group. -

The technological aspects of scCO2 fluid applications strongly depend on spatial–temporal fluctuations of its thermodynamic parameters. The region of these parameters’ maximal fluctuations on the p-T (pressure-temperature) diagram is called Widom delta. It has significant practical and fundamental interest. We offer an approach that combines optical measurements and molecular dynamics simulation in a wide range of pressures and temperatures. -

Thermodynamic Models & Physical Properties
Thermodynamic Models & Physical Properties When building a simulation, it is important to ensure that the properties of pure components and mixtures are being estimated appropriately. In fact, selecting the proper method for estimating properties is one of the most important steps that will affect the rest of the simulation. There for, it is important to carefully consider our choice of methods to estimate the different properties. In Aspen Plus, the estimation methods are stored in what is called a “Property Method”. A property method is a collection of estimation methods to calculate several thermodynamic (fugacity, enthalpy, entropy, Gibbs free energy, and volume) and transport (viscosity, thermal conductivity, diffusion coefficient, and surface tension). In addition, Aspen Plus stores a large database of interaction parameters that are used with mixing rules to estimate mixtures properties. Property Method Selection Property methods can be selected from the Data Browser, under the Properties folder as shown in Figure 13. To assist you in the selection process, the Specifications sheet (under the Properties folder) groups the different methods into groups according to Process type. For example, if you select the OIL-GAS process type, you will be given three options for the Base method: Peng-Robinson, Soave-Redlich-Kwong, and Perturbed Chain methods. These are the most commonly used methods with hydrocarbon systems such as those involved in the oil and gas industries. When you select a property method, you are in effect selecting a number of estimation equations for the different properties. You can see for example, to the right hand side of the Property methods & models box, what equations are being used. -
Study of Complex Properties of Binary System of Ethanol-Methanol at Extreme Concentrations
Study of complex properties of binary system of ethanol-methanol at extreme concentrations K Nilavarasi, Thejus R Kartha and V Madhurima* Department of Physics School of Basic and Applied Sciences Central University of Tamil Nadu Thiruvarur - 610101 *[email protected] Abstract At low concentrations of methanol in ethanol-methanol binary sys- tem, the molecular interactions are seen to be uniquely complex. It is observed that the ethanol aggregates are not strictly hydrogen-bonded complexes; dispersion forces also play a dominant role in the self- association of ethanol molecules. On the addition of small amount of methanol to ethanol, the dipolar association of ethanol is destroyed. The repulsive forces between the two moieties dominate the behavior of the binary system at lower concentration of methanol. At higher concentration of methanol (> 30%), the strength and extent (num- ber) of formation of hydrogen bonds between ethanol and methanol increases. The geometry of molecular structure at high concentra- tion favors the fitting of component molecules with each other. In- termolecular interactions in the ethanol-methanol binary system over the entire concentration range were investigated in detail using broad- band dielectric spectroscopy, FTIR, surface tension and refractive in- dex studies. Molecular Dynamics simulations show that the hydrogen bond density is a direct function of the number of methanol molecules present, as the ethanol aggregates are not strictly hydrogen-bond con- structed which is in agreement with the experimental results. arXiv:1611.05987v1 [physics.chem-ph] 18 Nov 2016 1 Introduction Ethanol and methanol strongly self-associate due to hydrogen bonding [1, 2, 3, 4]. -

However, the effects of adding an alcohol to a petrochemical fuel are yet to be fully understood. We report Fourier-transform infrared spectroscopy (FTIR) of ethanol/gasoline mixtures with systematically varied composition. Frequencies shifts and excess infrared absorbance are analyzed in order to investigate the mixture behavior at the molecular level. The spectroscopic data suggest that the hydrogen bonding between ethanol molecules is weakened upon gasoline addition, but the hydrogen bonds do not disappear. This can be explained by a formation of small ethanol clusters that interact via Van der Waals forces with the surrounding gasoline molecules. Furthermore, approaches for measuring the chemical composition of ethanol/gasoline blends by FTIR are discussed. For a simplistic approach based on the Beer-Lambert relation, an optimized set of parameters for quantitative measurements are determined. -

Determination of Density and Surface Tension in Ethanol and HFA 134a Mixtures Rob Johnson,1 Daniel I. Lewis,1 Paul M. Young,1 Henk K. Versteeg,2 and Graham Hargrave2 1Oz-UK Limited, Chippenham, Wiltshire UK 2Wolfson School of Mechanical, Electrical and Manufacturing Engineering, Loughborough University, Loughborough, UK KEYWORDS: binary mixtures, transient aerodynamic atomization model, metered dose inhaler, propellant INTRODUCTION Recent publications of a transient aerodynamic atomization model have highlighted saturated vapor pressure, density, viscosity and surface tension as key formulation properties governing pressurized metered dose inhaler (pMDI) droplet size [1-3]. Pharmaceutical pMDI formulations frequently use mixtures of propellant and excipients, such as ethanol, but the influence of such co-solvents on the aforementioned properties are not available in the literature. Hence, composition-dependent surface tension and density were experimentally determined for ethanol-HFA 134a mixtures. The expressions developed for density and surface tension are advantageous to understanding transient flows inside the actuator and atomization of pMDI formulations containing ethanol as a co-solvent [2]. MATERIALS AND METHODS Density The density of HFA 134a (Mexichem Fluor, Runcorn, UK) and absolute ethanol (Fisher Sci- entific, Loughborough, UK) mixtures have been determined at 20.2 ± 0.7°C utilizing a Comes DM density measuring device with Pyrex graduated (± 0.01 mL readability) 46.3 mL inner tube (DH Industries Limited, Laindon, UK). The device (Figure 1) was fitted with a Bespak BK 357 valve (Bespak Limited, King's Lynn, UK) to allow HFA 134a addition using a Pamasol P2016 467 468 Determination of Density and Surface Tension in Ethanol and HFA 134a Mixtures – Johnson et al. -
