This book was released on 2000-06-01 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report evaluates all available vapor-liquid equilibria (VLE) data from low-to-moderate pressures over the normal liquid water temperature range for the highly non-ideal aqueous ammonia solutions spanning nearly a century. The evaluation relies on all complete VLE data comprised of pressure- temperature-liquid and vapor compositions published over the last century to develop a temperature dependent model for the coefficients of the Wilson equation. The computations derived from the temperature dependent model are described by means of the program flowcharts and listings. Graphs of computed minima of the "best" Wilson coefficient pairs illustrate the statistical analysis of the experimental data. Tables of calculated deviations for three sets of Wilson coefficients corresponding to the individual and combined data sets demonstrate the utility of the model equations. Excellent agreement between the experimental and calculated liquid and vapor compositions is found for all but two data sets over the region of rapidly changing vapor composition up to 90 mole % of ammonia. This temperature dependent Wilson model offers a succinct representation of 100 years of what appear to be disparate pressure- temperature-composition VLE data.

Available in PDF, EPUB and Kindle. Book excerpt: This study extends a model for non-ideal solution behavior by considering the temperature dependence of the coefficients of the Wilson equation for aqueous ammonia. Twenty-seven sets of experimental PXY data up to I MPa (10 atm) pressure (N=284) are analyzed using an objective function based on the excess Gibbs free energy to determine the pair of Wilson coefficients for each set. Evaluation of these results supports the interpretation of the interaction parameters in Wilson's equation as temperature dependent entropy functions. Comparison of computed results is made with four categories of vapor-liquid equilibrium (VLE) data: (I) primary PTXY, (2) refined PTXY, (3) secondary PTXY or PTM, and (4) partial. Excellent agreement is found for all but two of these VLE data sets in the region of rapidly changing vapor composition up to 90 mol % of ammonia. A comparison also to three previously published isothermal pairs of Wilson coefficients shows that better agreement in Y for all three cases and in P for two cases is achieved with the entropic representation.
Download or read book Computation of Partial Vapor Pressures of Aqueous Volatile Organic Compound Solutions written by and published by . This book was released on 1996 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program is described for the evaluation of the partial vapor pressures of solution components dependent on the concentration in solution, total pressure, and temperature. The object of the program is to provide reliable values that represent the best estimate based on the large body of experimental data available in the literature. The basis of the estimate is the evaluation of the Wilson coefficients for calculating the activity coefficients of the components using an iterative least squares algorithm to minimize the excess Gibbs free energy of solution. The computational programs are applied to binary aqueous solutions of volatile organic compounds: methanol, ethanol, iso-propanol, acetone, and methyl ethyl ketone. The statistical evaluation of the results show that where the data base is large, in excess of 20 literature citations, the estimated error is around 1%. Smaller data bases, as in the case of methyl ethyl ketone with five citations, show poorer precision (e.g., around 3%). The results are applied to the evaluation of the vapor concentration dependence of the absorbance of selected peaks in the infrared spectrum of the compounds evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: A Textbook of Physical Chemistry: Second Edition provides both a traditional and theoretical approach in the study of physical chemistry. The book covers subjects usually covered in chemistry textbooks such as ideal and non-ideal gases, the kinetic molecular theory of gases and the distribution laws, and the additive physical properties of matter. Also covered are the three laws of thermodynamics, thermochemistry, chemical equilibrium, liquids and their simple phase equilibria, the solutions of nonelectrolytes, and heterogenous equilibrium. The text is recommended for college-level chemistry students, especially those who are in need of a textbook for the subject.
