This handbook is the only up-to-date, A to Z compilation of commercial and research zeolites. The volume presents complete patent-researched reference information on structural data, synthesis parameters, and characteristic properties. For each known zeolite there is an entry on all organics which crystallize a given structure, physical data, and applications. Data is presented in tabular or graphical form with minimal text, and a cross-referenced literature review is provided.

From areport by a Lieutenant Colonel W.A. Ross (Chern. News, Nov.15, 1878, p. 236). Progress did not accelerate during the next 50 years. McBain, in his clas sic 1932 book, The Sorption oi Gases by So lids, devoted a chapter to sorp tion by chabasite, other zeolites, and permeable crystals. McBain remarked that "great interest attaches to the finding of Weigel and Steinhoff [0. Weigel and E. Steinhoff, Z. Kris!., 61, 125 (1925{raquo}) that chabasite rapidly sorbs the vapors of water, methyl and ethyl alcohol and formie acid, whereas acetone, ether and benzene are largely excluded. The significance of their results was pointed out by McBain [J.W. McBain, Colloid. Syrnp. Mon., 20, 1 (1926{raquo}) and recognized by alliater writers. It is evident that the partially dehydrated chabasite forms a nearly perfect molecular sieve or a semipermeable membrane of extremely regular structure ... ". While the significance of the above observation may have been recog nized, it had little impact. Thus, an eminent pioneer in the synthesis and characterization af zeolites, Professor R.M. Barrer, spent nearly two dec ades (following his Ph. D. studies in the 1930s) developing a firm foundation for the rapid growth in scientific understanding and industrial applications of zeolites which has taken place during the last 30 years.

In view of the substantial progress made in the last decade in the fields of zeolites and related materials it was decided to go for an extended 2nd Edition of "Introduction to Zeolite Science and Practice". Unfortunately - as often is the case - this process took more time than expected by the Editors.In the mean time some new texts on zeolites were issued. Nevertheless, the combination of data, discussion and dedication provided by the present book is a unique coverage of the field, in the opinion of the Editors.In the present Edition the number of chapters rose from 16-22. The contributions can be divided into three categories: updated chapters by the original authors, updated chapters by an expanded or new team of authors and completely new chapters. This 2nd Edition also contains new chapters on "Zeolite-based supramolecular assemblies" (by Dirk De Vos and Pierre Jacobs, experts in this area) and on "The use of bulky probe molecules" (by Paul Kunkeler, Roger Downing and one of the Editors).Finally, the super large pore zeolites and the fast growing area of ordered mesoporous materials are dealt with by Eelco Vogt, Charlie Kresge and and Jim Vartuli. The latter two authors belong to the discoverers of the M41S family of mesoporous materials.

The efforts spent on many a scientific book cannot be justified, no matter how many words are said about it. The opposite is true for this book and a few brief remarks upon its publication. Within a short period of time, short even by all present standards, gel chromatography has gone through a development and experienced an acceptance that is unknown to any other method. From experience, the new and unique separation technique is today known and liked in all laboratories that are concerned with substances of high molecular weight; in others, the technique is known from hearsay, the least. Soon it became evident that a comprehensive coverage of the conceptual development, the theoretical principles, and the experimental technique of the new method would be desirable. This coverage is now offered by the book of an expert. Its author has personally participated in the development from its beginning and helped to promote it. He has made possible the gel chromatography, also of proteins, on thin layer plates; for lipophilic substances he has contributed considerably to the transition from water to organic solvent systems and developed theoretical concepts for a better understanding of the effects that are responsible for the separation. The book, so it appears to me, is pointing in new directions. The reader does not only expect a clear presentation of facts but also that of instructions for practical applications. Both these expectations have been met by the expert.

Molecular Sieves - Science and Technology covers, in a comprehensive manner, the science and technology of zeolites and all related microporous and mesoporous materials. Authored by renowned experts, the contributions to this handbook-like series are grouped together topically in such a way that each volume deals with a specific sub-field. Volume 5 complements Volume 4 (Characterization I) in that it is devoted to the characterization of molecular sieves by a variety of non-spectroscopic techniques (Characterization II). Thus, Volume 5 comprises Chemical Analysis, Thermal Analysis, Pore-Size Characterization by Molecular Probes, Characterization by 129Xe NMR, Coke Characterization, Synthesis and Characterization of Isomorphously Substituted Molecular Sieves.

Molecular Sieves - Science and Technology covers, in a comprehensive manner, the science and technology of zeolites and all related microporous and mesoporous materials. Authored by renowned experts, the contributions are grouped together topically in such a way that each volume of the book series deals with a specific sub-field. Volume 4 covers the characterization of molecular sieves with the help of the most important spectroscopic techniques (Characterization I), i.e. IR, Raman, NMR, EPR, UV-VIS Spectroscopy, X-ray absorption, photoelectron and Mössbauer Spectroscopy. Theory, experiment and application in selected examples are discussed.
