Modern flavours and fragrances are complex formulated products, containing blends of aroma compounds with auxiliary materials, enabling desirable flavours or fragrances to be added to a huge range of products. From the identification and synthesis of materials such as cinnamaldehyde and vanillin in the 19th Century to the current application of advanced analytical techniques for identification of trace aroma compounds present in natural materials, the flavour and fragrance industry has developed as a key part of the worldwide specialty chemicals industry. With contributions mainly coming from industry based experts, Chemistry & Technology of Flavours and Fragrances provides a detailed overview of the synthesis, chemistry and application technology of the major classes aroma compounds. With separate chapters covering important technical aspects such as the stability of aroma compounds, structure – odour relationships and identification of aroma compounds, this book will be essential reading for both experienced and graduate level entrants to the flavour & fragrance industry. It will also serve as an important introduction to the subject for chemists and technologists in those industries that use flavours and fragrances, eg food, cosmetics & toiletries, and household products.

Modern flavours and fragrances are complex formulated products containing blends of aroma compounds with auxiliary materials, enabling desirable flavours or fragrances to be added to a huge range of products. The flavour and fragrance industry is a key part of the worldwide specialty chemicals industry, yet most technical recruits have minimal exposure to flavours and fragrances before recruitment. The analytical chemistry of flavour and fragrance materials presents specific challenges to the analytical chemist, as most of the chemicals involved are highly volatile, present in very small amounts and in complex mixtures. Analytical Methods for Flavor and Fragrance Materials covers the most important methods in the analysis of flavour and fragrance materials, including traditional and newly emerging methodologies. It discusses the capabilities of the various analytical methods for flavour and fragrance analysis and guides the newcomer to the most appropriate techniques for specific analytical problems.

This textbook provides an integral and integrated treatment of industrial-relevant problems for students of both chemistry and chemical engineering. As such, this work combines the four disciplines of chemical technology – chemistry, thermal and mechanical unit operations, chemical reaction engineering and general chemical technology – and is organized into two main parts. The first covers the fundamentals, as well as the analysis and design of industrial processes, while the second section presents 20 concrete processes, exemplifying the inherent applied nature of chemical technology. These are selected so that they all differ with respect to at least one important aspect, such as the type and design of the reactor, the chemistry involved or the separation process used. As a result, readers will recapitulate, deepen and exercise the chemical and engineering principles and their interplay, as well as being able to apply them to industrial practice. Instructive figures, rules of thumb for swift but reliable estimating of parameters, data of chemical media, and examples utilizing data from industrial processes facilitate and enhance the study process. A small general survey of selected modern trends, such as multifunctional and micro reactors, or new solvents for homogeneous catalysis, such as ionic liquids, point out to the reader that this is not a concluded discipline, but a developing field with many challenges waiting to be solved.
The first seven metals in the periodic table are lithium, beryllium, sodium, magnesium, aluminium, potassium and calcium, known collectively as the “lightest metals”. The growing uses of these seven elements are enmeshing them ever more firmly into critical areas of 21st century technology, including energy storage, catalysis, and various applications of nanoscience. This volume provides comprehensive coverage of the fundamentals and recent advances in the science and technology of the lightest metals. Opening chapters of the book describe major physical and chemical properties of the metals, their occurrence and issues of long-term availability. The book goes on to disucss a broad range of chemical features, including low oxidation state chemistry, organometallics, metal-centered NMR spectroscopy, and cation-π interactions. Current and emerging applications of the metals are presented, including lithium-ion battery technology, hydrogen storage chemistry, superconductor materials, transparent ceramics, nano-enhanced catalysis, and research into photosynthesis and photoelectrochemical cells.
