This book was released on 2022-12-12 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microemulsions are known for their versatile properties widely utilized in fundamental research and industrial applications. They are thermodynamically stable mixtures structured on a colloidal length scale with an amphiphilic film separating water- and oil-rich domains. However, recent studies claim the existence of “surfactant-free microemulsions,” which exhibit structures on a molecular length scale. By means of systematic phase behavior and scattering experiments, this dissertation provides deep insights into the pathway from simple solutions to weakly and strongly structured microemulsions. With bulk-contrast SANS, the scattering behavior of a simple solution system made of water, cyclohexane, 1- and 2-propanol was found to be dominated by critical composition fluctuations (Ornstein-Zernike). Further analysis of critical phenomena revealed the critical exponent doubling that follows the scaling law γ ~ “2” ν. On the other hand, weak scattering signals described with a new model were detected in the film-contrast SANS data due to the nearby tricritical point (TCP). After crossing the TCP, the formation of well-defined amphiphilic films was demonstrated by increasing the amphiphilicity of the amphiphile. Subsequently, the influence of modifications of the amphiphilic film by adding novel diblock polymers was studied. As a result, enhanced efficiency and strengthened structural ordering were achieved in typical alkane microemulsions and novel CO2 microemulsions. Finally, the properties of industry-relevant microemulsions were investigated in two application-oriented projects. One project focused on the phase behavior and the microstructure of polyol-rich CO2 microemulsions, which can be used for the polyurethane (PU) foam production with cell sizes of a few micrometers. The other project focused on the formulation of optimum microemulsions stabilized by highly efficient extended surfactants. The experimental parameters from phase behavior studies helped determine the coefficients of the HLD equation, which can serve as a prediction tool for tackling a wide variety of formulation problems. Above all, this doctoral dissertation elucidated the pathway toward structured microemulsions and demonstrated versatile aspects of microemulsions’ applications.

Available in PDF, EPUB and Kindle. Book excerpt: Microemulsions: Theory and Practice covers the development of the theory and practice of microemulsion systems. This book is divided into seven chapters that explore the physics and chemistry of microemulsions. This book deals first with the commercial history of microemulsions, from the discovery of carnauba wax emulsions to polymer emulsions. This topic is followed by discussions on the theoretical aspects of microemulsion formulation techniques and the design of other products. The subsequent chapter describes the microemulsion formulation with less solubilizer or emulsifier together with their optical properties. A chapter examines the mixed film theory that explains the dispersions, oil-water interface, and inferences in microemulsions. Another chapter considers the role of microemulsions in micellar solutions and their relations to the concentrations of different compounds. This chapter also looks into the association phenomena of three-component phase equilibria diagrams and liquids crystals to microemulsions. The concluding chapter discusses the role of the capillary and hydrostatic forces on the entrapment of oil in the reservoir and the necessary conditions for the displacement of entrapped oil. The important properties and economic aspects of a microemulsion slug required for the tertiary oil recovery are also covered in this chapter.

Available in PDF, EPUB and Kindle. Book excerpt: This book takes an interface science approach to describe and understand the behavior of the dispersions we call emulsions, microemulsions and foams. The one thing all these dispersions have in common is the presence of surface-active species (surfactants) adsorbed at the interfaces between the two fluid phases that make up the emulsions, microemulsions or foams. The interfacial layers formed by the surfactants control most of the properties of the dispersions. The book describes the properties of interfacial layers, thin films and bulk fluids used in the elaboration of the various dispersions and it explains how such properties relate to the dispersion properties of these soft matter systems: structure, rheology and stability. These dispersion properties are far from being fully understood, in particular foam and emulsion stability. In discussing the state of the art of the current knowledge, the author draws interesting parallels between emulsions, microemulsions and foams that enlighten the interpretation of previous observations and point to a deeper understanding of the behavior of these materials in the future.

This book was released on 2022-06-21 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid multiphase processes represent a promising option for realizing novel, efficient, and sustainable production processes, as required for the transformation towards climate-neutral manufacturing processes. This volume presents the results obtained over twelve years in the DFG-funded collaborative project Transregio 63 “Integrated Chemical Processes in Liquid Multiphase Systems”. In an interdisciplinary approach to the design and operation of such processes, essential principles of Green Chemistry are realized, such as using long-chain olefins as model representatives of renewable raw materials, highly effi cient catalysts, and green solvents, linked with process optimization to improve energy and material efficiency. Experts from different fields addressed all steps of the development process, from the description of the reactions on the molecular level via thermodynamics and the design of efficient separation processes to the operation of entire miniplants for liquid multiphase production processes. Thus, the complete development chain from the first reaction-related investigations in the laboratory to the technological realization in miniplants with model-based control is demonstrated. Numerous methodological innovations are proposed and validated using several innovative phase systems (thermomorphic multiphase systems, microemulsion systems, Pickering emulsions) and homogeneously catalyzed reactions. Engineers and chemists from the chemical industry as well as advanced students and researchers will get valuable insights into the physico-chemical phenomena in chemical multiphase processes and benefit from recommendations concerning methods for the selection of phase systems and rapid model-based process development.
