The demands for green and sustainable synthetic methods in the fields of healthcare and fine chemicals, combined with the pressure to produce these substances expeditiously and in an environmentally benign fashion, pose significant challenges to the synthetic chemical community. Green chemistry can avoid pollution by utilizing techniques that are environmentally friendly by design and one of the best green techniques is the use of microwave (MW) assisted aqueous synthetic protocols. Fusing MW technique with water (as a benign reaction medium) can offer an extraordinary synergistic effect with greater potential than these two individual components in isolation. Selective microwave heating can be exploited to develop a high yield protocol and the use of water expedites the MW-protocol with more energy efficiency. This book provides an overview of the various processes developed using aqueous microwave chemistry and is written for chemists, chemical engineers and researchers in the early stages who want to develop sustainable and green processes. Written by well known microwave experts, the book is a comprehensive examination of the field and is the first book that deals strictly with aqueous microwave chemistry and represents a significant effort towards green chemistry. It covers all the microwave-assisted aqueous reactions in depth, including heterocycle synthesis, metal catalysis, enzyme catalysis, polymer synthesis, nanomaterials synthesis and nano-catalysis. Each chapter contains representative experimental procedures, helping the reader quickly replicate some of the experiments to gain hands-on experience.

Tailored to the needs of medicinal and natural products chemists, the second edition of this unique handbook brings the contents up to speed, almost doubling the amount of chemical information with an additional volume. As in the predecessor, a short introductory section covers the theoretical background and evaluates currently available instrumentation and equipment. The main part of the book then goes on to systematically survey the complete range of published microwave-assisted synthesis methods from their beginnings in the 1990s to mid-2011, drawing on data from more than 5,000 reports and publications. Throughout, the focus is on those reactions, reagents and reaction conditions that work, and that are the most relevant for medicinal and natural products chemistry. A much expanded section is devoted to combinatorial, highthroughput and flow chemistry methods.

Microwave-Assisted Sample Preparation for Trace Element Analysis describes the principles, equipment, and applications involved in sample preparation with microwaves for trace element analysis. The book covers well-established applications as well as new trends in this field. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. The use of microwaves in sample preparation has increased in recent decades. Several applications of microwaves for sample preparation can be found in the literature for practically all types of sample matrices, especially for the determination of trace elements by atomic spectrometric techniques, safely and cleanly reducing the time involved in this step. Microwave-assisted sample preparation is not only a tool for research but also for routine analysis laboratories; the state-of-the-art in sample preparation in trace element analysis. This book is the only resource for chemists specifically focused on this topic. The first book to describe the principles, equipment, and applications in microwave-assisted sample preparation Written by experts in the field who provide a comprehensive overview of the important concepts Introduces new alternatives and trends in microwave-assisted techniques

Allowing many chemical reactions to be completed within minutes, microwave heating has revolutionized preparative chemistry. As a result, this technology has been widely adopted in both academic and industrial laboratories. Integrating microwave-assisted chemistry into undergraduate laboratory courses enables students to perform a broader range of reactions in the allotted lab period. As a result, they can be introduced to chemistry that would otherwise have been inaccessible due to time constraints (for example, the need for an overnight reflux). Laboratory Experiments Using Microwave Heating provides 22 experiments encompassing organic, inorganic, and analytical chemistry performed using microwave heating as a tool, making them fast and easy to accomplish in a laboratory period. Utilizing the time-saving experiments described in this book also permits students to repeat experiments if necessary or attempt additional self-designed experiments during the lab course. A number of the chemical transformations use water as a solvent in lieu of classical organic solvents. This contributes to greener, more sustainable teaching strategies for faculty and students, while maintaining high reaction yields. All the experiments have been tested and verified in laboratory classes, and many were even developed by students. Each chapter includes an introduction to the experiment and two protocols—one for use with a smaller monomode microwave unit employing a single reaction vessel and one for use with a larger multimode microwave unit employing a carousel of reaction vessels.

Most of the chemical manufacturing industries use electricity generated from coal for heating puropses. Use of coal generates oxides of carbon, nitrogen and sulphur which are responsible for Environmental Pollution. In view of this, attempts have been made to use alternate energy processes. This book deals with the use of microwaves, sonication and photo activation as alternate energy sources. Besides these energy processes, some reactions can also be carried out just by mixing of the reactants in a pestle-mortar or by just heating at low temperatures (40-70 degrees C). These alternate energy processes will go a long way in minimizing the pollution of the environment.
