Practical Sonochemistry: Power Ultrasound Uses and Applications
Timothy J. Mason, Dietmar Peters
Softcover, 165 Pages
2nd Edition, 2003
This updated text for advanced students and teachers in chemistry and chemical engineering conveys increasing growth in applications and equipment. With descriptions of new ultrasonic equipment and laboratory uses for industry. New material includes methods for estimating ultrasonic energy entering the system (dosimetry).
Ultrasound baths used for cleaning purposes are already a fixture in some laboratories, but most people don’t know what it is that makes this cleaning of dirty flasks possible. Even if they actually would be able to carry out reactions in the ultrasound bath, many still hesitate to do so, since researchers don’t exactly consider ultrasound to be “reproducible”. For this reason, the technique’s potential is yet unrealized in many quarters, and is limited to more short-term applications, such as initiating Grignard reactions.
Timothy J. Mason and Dietmar Peters have recognized that a detailed and easily understood explanation of sonochemistry and the required techniques is indispensible for demystifying the use of ultrasound. Three-quarters of their book is devoted to explanations of the physical effects and what sort of equipment can be used, but it also covers what possibilities are available for chemical production. The text is easy to understand by students as well as researchers in the chemical and engineering sciences, and contains practical tips such as how aluminum foil can be used to find where the ultrasound is maximally effective.
Later on, the reader will find several interesting reactions, for which detailed procedures are provided. Since the most interesting procedures are presented together with practical tips, the experiments lend themselves nicely to being performed in a student lab. Despite the experiments being relatively few in number, the hints provided can be adopted for use in the reader’s own work. Even with multiphase reactions, or those in which highly reactive intermediate such as carbenes or radicals are produced, interesting results can be obtained through the use of ultrasound conditions.
With this detailed physical and technical description of ultrasound, the authors have succeeded in removing some of the obstacles to the broader implementation of the technique. The carefully selected reactions, which contain a great deal of information, foster the mindset that sonochemistry can be truly practical. It is Tim Mason‘s hope that ultrasound will not be simply a routine laboratory technique, but rather become an exciting field of research. With the present book, the authors have definitely laid the ground work for such a development..
