For the first time: A comprehensive Overview on Resins! Resins nowadays are still the subject of much interest, with applications in many branches of industrial production. Increasingly stringent specific market requirements and the demand for better quality control and product consistency mean that chemists, engineers, and application technicians are not merely satisfied with the knowledge of the physical data of the basic chemical products they are using. The raw materials, their production processes and special physical and chemical characteristics relevant to their applications are increasingly of interest. This book points out the extent to which raw materials, manufacturing processes, and chemical composition of resins influence their application and performance.
Many modern medicines, for example blood derivatives, vaccines, cytostatic drugs, and antibiotics, but also soluble coffee, have one thing in common: freeze-drying is the best method of transforming the perishable substances into a form that keeps well and allows the substances to be stored before being returned almost to their natural state. This book describes the rules of freeze-drying. The critical process data is not just presented theoretically but explained with regard to practical examples. Application of freeze-drying processes is the main emphasis of this book. Many years of experience in the freeze-drying business allow the author to present valuable criteria for the selection of laboratory or industrial plants. Evaluation of the latest publications guarantees state-of-the-art coverage of information. Even modern topics, e.g., validation of processes or estimation of acceptable variances from preset values, are taken into account. These valuable tips make the book indispensable for everybody working in the freeze-drying business.
This is a book for developers of catalysts, and for practitioners working in the field of design, operation, and optimization of chemical reactors in which heterogeneous catalysis is performed. It is designed to give a better understanding of the phenomena which can influence catalyst performance. Since two disciplines, chemistry and chemical engineering, meet in catalyst research and development, this book covers the chemical point of view for engineers, and the engineering point of view for chemists. It starts with an introduction explaining selectivity, activity and effectiveness providing the fundamentals for the newcomer. Catalyst preparation and catalyst testing are also described. A method is introduced that can be used to calculate the effectiveness of catalyst pellets as a function of shape, size, pore size, type of kinetics and diffusion, and temperature and pressure conditions. Optimization of catalysts and troubleshooting are also covered. This is a book without any rilvals because of its practical relevance.
Resulting from the premier forum for pesticide development and use, this volume provides comprehensive coverage and even captures emerging technologies within the industry. All facets of pesticides are addressed here, including agriculture, agrochemicals, and environmental health aspects, as well as such global issues as food quality and safety.
A practical summary of the technical and technological as well as nutritional and physiological properties attained through the targeted selection of raw materials and the corresponding production processes. The two authors come from the world's leading gelatine company and adopt here an international approach, enabling their knowledge to be transferred between the various application areas on a global scale. Following an introduction to and the history of gelatine, the text surveys the global industry and current trends, before going on to analyze the basic physical, chemical and technological properties of gelatine. Manufacturing, including quality and safety and the processing of powder, instant gelatine and hydrolysate are dealt with next, prior to an in-depth review of applications in beverages and foodstuffs, pharmaceuticals, health and osteoarthritis, among others. The whole is rounded off by future visions and a useful glossary. Aimed at all gelatine users, heads and technicians in production and quality control, product developers, students of food science and pharmacy as well as marketing experts within the industry and patent lawyers.

Membrane Technology – a clean and energy saving alternative to traditional/conventional processes. Developed from a useful laboratory technique to a commercial separation technology, today it has widespread and rapidly expanding use in the chemical industry. It has established applications in areas such as hydrogen separation and recovery of organic vapors from process gas streams, and selective transport of organic solvents, and it is opening new perspectives for catalytic conversion in membrane reactors. Membrane technology provides a unique solution for industrial waste treatment and for controlled production of valuable chemicals. This book outlines several established applications of membranes in the chemical industry, reviews the available membranes and membrane processes for the field, and discusses the huge potential of this technology in chemical processes. Each chapter has been written by an international leading expert with extensive industrial experience in the field.
Despite the fact that more than 90% of production processes in industry are catalyzed, most chemists and engineers are restricted to trial and error when searching for the proper catalyst. This book is the first emphasizing industrial aspects of catalysis and also particularly well suited to studying on one's own. It is dedicated to both, homogeneous and heterogeneous catalysis and in this second, edition biocatalysis, electrocatalysis, photocatalysis and asymmetric catalysis are also included; topics like zeolites, metals and olefin catalysis are now discussed in more detail. The book aids practically oriented readers in becoming familiar with the processes of catalyst development and testing and therefore deals with aspects of test planning, optimization and reactor modeling and simulation with the easy-to-learn PC program POLYMATH. Well over 100 exercises help to test and consolidate the gained knowledge.
