This Sixteenth Edition of Langes Handbook of Chemistry takes on a new format under a new editor.

Nevertheless, the Handbook remains the one-volume source of factual information for chemists and chemical engineers, both professionals and students. The aim of the Handbook remains to provide sufficient data to satisfy the general needs of the user without recourse to other reference sources. The many tables of numerical data that have been compiled, as well as additional tables, will provide the user with a valuable time-saver. The new format involves division of the Handbook into four major sections, instead of the 11 sections that were part of previous editions. , General Information and Conversion Tables, contains all of the general information and conversion tables that were previously found in different sections of the Handbook. In also contains expanded information relating to the names and properties of condensed polynuclear aromatic compounds.

Enthalpies and Gibbs Energies of Formation, Entropies, and Heat Capacities of Organic and Inorganic Compounds, and Heats of Melting, Vaporization, and Sublimation and Specific Heat at Various Temperatures, are also presented in for organic and inorganic compounds, as well as information on the critical properties (critical temperature, critical pressure, and critical volume). As in the previous edition, ), has been retained as it offers valuable information and procedures for laboratory methods. As stated in the prefaces of earlier editions, every effort has been made to select the most useful and reliable information and to record it with accuracy. It is hoped that users of this Handbook will continue to offer suggestions of material that might be included in, or even excluded from, future editions and call attention to errors. These communications should be directed to the editor through the publisher, McGraw-Hill. JAMES G.

This new edition, the fifth under the aegis of the present editor, remains the one-volume source of factual information for chemists, both professionals and studentsthe first place in which to look it up on the spot. The aim is to provide sufficient data to satisfy all ones general needs without recourse to other reference sources. A user will find this volume of value as a time-saver because of the many tables of numerical data that have been especially compiled. Descriptive properties for a basic group of approximately 4300 organic compounds are compiled in , an increase of 300 entries. All entries are listed alphabetically according to the senior prefix of the name.

The data for each organic compound include (where available) name, structural formula, formula weight, Beilstein reference (or if un- available, the entry to the Merck Index, 12th ed.), density, refractive index, melting point, boiling point, flash point, and solubility (citing numerical values if known) in water and various common organic solvents. Structural formulas either too complex or too ambiguous to be rendered as line formulas are grouped at the bottom of each facing double page on which the entries appear. Alternative names, as well as trivial names of long-standing usage, are listed in their respective alphabetical order at the bottom of each double page in the regular alphabetical sequence. Another feature that assists the user in locating a desired entry is the empirical formula index. on General Information, Conversion Tables, and Mathematics has had the table on general conversion factors thoroughly reworked. Similarly the material on Statistics in Chemical Analysis has had its contents more than doubled.

Descriptive properties for a basic group of inorganic compounds are compiled in , Properties of Atoms, Radicals, and Bonds, have been significantly enlarged. For example, the entries under Ionization Energy of Molecular and Radical Species now number 740 and have an additional column with the enthalpy of formation of the ions. Likewise, the table on Electron Affinities of the Elements, Molecules, and Radicals now contains about 225 entries. The Table of Nuclides has material on additional radionuclides, their radiations, and the neutron capture cross sections. Revised material for Section 5 includes the material on surface tension, viscosity, dielectric constant, and dipole moment for organic compounds. In order to include more data at several temperatures, the material has been divided into two separate tables.
