Emulsions, Foams, and Suspensions


Book Description

Until now colloid science books have either been theoretical, or focused on specific types of dispersion, or on specific applications. This then is the first book to provide an integrated introduction to the nature, formation and occurrence, stability, propagation, and uses of the most common types of colloidal dispersion in the process-related industries. The primary focus is on the applications of the principles, paying attention to practical processes and problems. This is done both as part of the treatment of the fundamentals, where appropriate, and also in the separate sections devoted to specific kinds of industries. Throughout, the treatment is integrated, with the principles of colloid and interface science common to each dispersion type presented for each major physical property class, followed by separate treatments of features unique to emulsions, foams, or suspensions. The first half of the book introduces the fundamental principles, introducing readers to suspension formation and stability, characterization, and flow properties, emphasizing practical aspects throughout. The following chapters discuss a wide range of industrial applications and examples, serving to emphasize the different methodologies that have been successfully applied. Overall, the book shows how to approach making emulsions, foams, and suspensions with different useful properties, how to propagate them, and how to prevent their formation or destabilize them if necessary. The author assumes no prior knowledge of colloid chemistry and, with its glossary of key terms, complete cross-referencing and indexing, this is a must-have for graduate and professional scientists and engineers who may encounter or use emulsions, foams, or suspensions, or combinations thereof, whether in process design, industrial production, or in related R&D fields.

Colloidal Dispersions


Book Description

From the basics to the most recent developments- A concise review of suspensions, emulsions, and foams Updating and expanding their highly popular Colloidal Systems and Interfaces, Ian Morrison and Sydney Ross now provide authoritative coverage of the concepts and techniques applicable to suspensions, emulsions, and foams. Concisely yet thoroughly encompassing the significant developments of the past fourteen years, Colloidal Dispersions: Suspensions, Emulsions, and Foams describes a wide range of topics, including particles in liquids, interactions at interfaces, surfactants, and the technology of emulsions and foams. Industrial chemists and chemical engineers will discover among the book's insights recently developed computer-based methods that offer fast, precise measurements of particle concentration, size, and charge by acoustics, application of acid-base concepts to adsorption, the role of electric charges in nonpolar media, and the fundamentals of nanotechnology. This new edition includes: * Updated material and major advances in the field, including the development of new equipment * In-depth instruction on methods for producing emulsions and suspensions * Extensive industrial and practical applications of general principles * Expanded sections on particle sizing, nonpolar dispersions, and polymer stabilization




Formulation Technology


Book Description

Many chemical substances or compounds - organic or inorganic, natural or synthetic - are not used in their pure form. In order for the active ingredient to be most effective or to obtain the ideal delivery form for the market, the actual synthesis and purification steps are followed by formulation to give end products that range from powders, agglomerates, and granules to suspensions, emulsions, microemulsions, microcapsules, instant preparations, liposomes, and tablets. Formulation combines colloid and surface chemistry with chemical process engineering; sometimes it consists of a simple mixing operation, sometimes it requires an entire series of rather complicated engineering procedures such as comminution, dispersion, emulsification, agglomeration or drying. This book covers basic physico-chemical theory as well as its applications in the chemical industry for the production of pharmaceuticals, agrochemicals, pigments and dyes, food, detergents, cosmetics and many other products; it also provides chemists and chemical engineers with the necessary practical tools for the understanding of the structure/ activity relationship.




Rheology of Dispersions


Book Description

A dispersion is a system of unmixable phases in which one phase is continuous and at least one is finely distributed. Examples are found in many industrial applications, including emulsions, suspensions, foams, and geld. The control of their flow characteristics - rheology - is essential in their preparation, long-term physical stability and application. Filling the need for a practical, up-to-date book connecting the stability/instability of the dispersion to its rheological behavior, this title aids in understanding the principles of rheology and the techniques that can be applied. From the contents: * General Introduction * Interparticle Interactions and Their Combination * Principles of Viscoelastic Behavior * Rheology of Suspensions * Rheology of Emulsions * Rheology of Modifiers, Thickeners, and Gels * Use of Rheological Measurements for Assessment and Prediction of the Long-Term Physical Stability of Formulations (Creaming and Sedimentation)
