CRC Handbook of Chemistry and Physics - 97th Edition (2016)

picture: 

This 97th Edition of the CRC Handbook of Chemistry and Physics is the first to be produced by a new procedure in which the full content is maintained in a database from which both the print version and the Internet edition are generated. This will assure that chemical names, formulas, and basic physical properties are consistent throughout the work. Thus if a melting point or density is replaced by a more accurate value, the new value will be propagated into all tables containing that substance. We believe this is an important step in maintaining the reputation of the CRC Handbook as a source for the most current information available.

In the process of creating this master database, many small updates have been made throughout the book. In addition, several major updates and expansions have been made in this edition. These include:

 

• CODATA Values of the Fundamental Physical Constants – The new set of CODATA constants, which will be the basis of the upcoming revision of the basic international standards of measurement

• Standard Atomic Weights – 2015 changes made by IUPAC

• Atomic Masses and Abundances – Update of isotopic abundances

• Surface Tension of Common Liquids – Addition of new compounds and updates of values

• Basic Instrumental Techniques of Analytical Chemistry – Expansion to cover colorimetry and refractometry

• Photon Attenuation Coefficients – Addition of absorption edge data

• Classification of Electromagnetic Radiation – Update with modern terminology

• Astronomical Constants – Update with new IAU recommended constants

• Solar System Properties – Addition of newly discovered satellites of the planets

• Interstellar Molecules – Complete list of molecules observed in space to date

• Major World Earthquakes – Update through 2015

• Atmospheric Concentration of CO2 – Update through 2015

• Global Temperature Trend - Update through 2015

• Abbreviations Used in the Assessment and Presentation of Laboratory Hazards – Expansion

• Relative Dose Ranges from Ionizing Radiation – Expansion

• Threshold Limits for Airborne Contaminants – Update to 2015 recommendations

• Chemical Carcinogens – Inclusion of 2015 recommendations of the National Toxicology Program

Two new topics were added in the 97th Edition:

• Surface Active Chemicals – Table of properties of the most important surfactants (solubility, physical constants, critical micelle concentration, hydrophilic-lipophilic balance, etc.)

• Nanomaterial Safety Guidelines – Definition of terms in nanoscience; guidelines for safe handling and disposal The Index to the CRC Handbook covers properties, processes, general concepts, and classes of substances.

 

Space does not permit an index to individual chemical compounds, but the Internet Edition provides searching for compounds on the basis of name, synonym, molecular formula, CAS Registry Number, or structure. For the book edition, indexes to the tables “Physical Constants of Organic Compounds” and “Physical Constants of Inorganic Compounds” are available in PDF form by e-mail request to fiona. macdonald@taylorandfrancis.com. The success of the Handbook is very dependent on feedback from its users. The Editor-in-Chief appreciates any suggestions from readers on proposed new topics for the Handbook or comments on how the usefulness of the Handbook may be improved in future editions. Please send your comments to fiona.macdonald@taylorandfrancis.com. Numerous international experts make key contributions to the Handbook. These contributors are listed on pages immediately following the Preface. Their efforts play a key role in the quality and diversity of the subject matter covered in the Handbook. The sound advice and guidance of the Editorial Advisory Board members, who are listed in the front matter, is very much appreciated. Fiona Macdonald, Publisher – Chemical & Life Sciences, CRC Press/Taylor & Francis Group has been of great assistance and support in providing oversight to ensure that the Handbook continues to satisfy the needs of the user community. Thanks are also due to Linda Manis Leggio, Pam Morrell, Theresa Gutierrez, and James Yanchak for their detailed, cooperative work and extreme care in the production of the Handbook. Special thanks are due to Chris Muzny and Thomas Bruno for their assistance in support of the Editor-in-Chief. Finally, it is with deep regret that I must report the passing of W. M. (Mickey) Haynes, Editor-in-Chief, during the preparation of this edition. During his seven years as Editor he guided the CRC Handbook into new scientific areas and continued the emphasis on the highest quality of scientific information. He was a successful leader as the book entered its second century.
