Surface Tension of Pure Liquids and Binary Liquid Mixtures: (Supplement to IV/16) (Landolt-Börnstein: Numerical Data and Functional Relationships in Science and Technology - New Series)

1 Introduction Data extract from Landolt-Börnstein IV/24: Surface Tension of Pure Liquids and Binary Liquid Mixtures 1.1 Selection of data This supplement updates Landolt-Börnstein's New Series Group IV (Physical Chemistry) Volume 16, S- face Tension of Pure Liquids and Binary Liquid Mixtures, published in the year 1997 1997WOH1. The update provides experimental data published in the years 1997 to 2006. The ?nal date for including data was December, 31st, 2006. Specialization and selection of data for this new update follows the intentions of the original volume. The focus is on non-electrolyte systems, and only data for pure liquids and binary liquid mixtures at normal pr- sure (or in some single cases at saturation vapor pressure) were taken into account for this volume. For m- tures, this data collection is restricted to binary liquid mixtures, i.e. no ternary systems and also no solutions of any solids, salts, electrolytes, polymers are included here. Surfactant solutions or micellar systems in water or other ?uids were not considered either. At least, also molten metals and metallic alloys, molten salts, molten glasses and other high-temperature melts were not taken into account. As the amount of data collected between 1997 and 2006 exceeds the available space for printing by far, the volume has an electronic version containing additional data which is available on www.landolt-boernstein.

Surface Tension of Pure Liquids and Binary Liquid Mixtures (Landolt-Börnstein: Numerical Data and Functional Relationships in Science and Technology - New Series / Physical Chemistry)
(Scientific and technological research on many areas needs...)
Scientific and technological research on many areas needs data on surface tension of the used materials, e.g.: thin layer technologies, microelectronics, electronic functional units, sol-gel technologies for material production, development of compound materials, phase separation techniques, matrix systems for chemical reactions, drug carriers, treatment of raw materials, etc. Due to this large interest it was decided to publish this volume on surface tension of liquids and binary liquid mixtures. Since the amount of data exceeds the available space for printing, only one recommended data set for each substance is printed. Therefore, this volume contains a CD-ROM where all available data are provided. The data of the 6th Edition of Landolt- Börnstein Vol. II/3, 1956 (!) are included in this volume.

Vapour-Liquid Equilibrium Data of Binary Polymer Solutions: Vapour Pressures, Henry-Constants and Segment-Molar Excess Gibbs Free Energies (Physical Sciences Data)
(Knowledge of vapour-liquid equilibrium (VLE) data is nece...)
Knowledge of vapour-liquid equilibrium (VLE) data is necessary for the proper understanding of a large number of industrial and laboratory processes. Such data allow a grasp of the thermodynamic behaviour of mixtures, the study of intermolecular interactions and enable insight into the molecular nature of mixtures. They are also a basis for the development of theoretical thermodynamic models. Scientists and engineers will obviously benefit from a careful collection of the existing data. This book aims to provide a reliable collection of such data. Original data have been gathered from around 450 literature sources, including 80 journals and a number of dissertations and diploma papers. Previously unpublished data from the Thermodynamic Department of the former Merseburg-University and the author's own data sets are included. The VLE-data are divided into three chapters: 1. Vapour pressures of binary polymer solutions (or solvent activities) - Chapter 2 2. Segment-molar excess Gibbs free energies of binary polymer solutions (in the form of Redlich-Kister parameters) - Chapter 3 3. Weight fraction Henry-constants for gases and vapours in molten polymers (from inverse gas-liquid chromatography measurements) - Chapter 4. A short introduction to the experimental methods and data reduction is included as Chapter 1. There are indexes for the polymers and solvents cited.
