[资源] Handbook of chemistry and physics（2003-2004）

PERFACE

The 84th Edition of the CRC Handbook of Chemistry and Physics features a completely new
version of the most heavily used table, Physical Constants of Organic Compounds. This is the
first revision of the table since 1994. Compounds have been selected for inclusion in the new
table by a careful screening of lists of organic compounds that are important in laboratory
research, industrial chemistry, environmental protection, drug development, teaching, and other
active areas. In this way priorities were established for choosing the most significant compounds
out of the millions of organic substances that have been reported in the literature. Property data
for the selected compounds have been updated, and new structure diagrams, which show much
more detail than the previous structures, have been drawn for all the compounds.

This Internet version of the 84th Edition has added 17 new subsections that can be accessed as
interactive tables. These include tables on Heat of Combustion, Activity Coefficients,
Refrigerants, Amino Acids, Chemical Carcinogens, Laboratory Solvents, and other topics. The
search screens have been modified to make them more user friendly, and there is now a subject
index that permits boolean searching on the name of a physical property and the identifiers of a
chemical substance (name, formula, or CAS Registry Number). An option has been added to the
table displays that permits locking the left-most column, which usually contains the chemical
name, when scanning a wide table. Tool-tips that explain the data in a column now appear when
the cursor is held over that column heading, and it is now possible to export the results of a search
directly into an Excel file.

Other new features of the 84th Edition include:
• An update and expansion of the table of Critical Constants of Fluids, with many new
compounds and recently published data
• A new version of Properties of Refrigerants, which covers fluids now used in
refrigeration systems and those being considered as substitutes
• A new table on Fermi Energy and Related Properties of Metals
• New tables of practical laboratory data such as Flame and Bead tests, Flame
Temperatures, and Density of Ethanol-Water Mixtures
• An update of lists of Chemical Carcinogens and Interstellar Molecules.

The Handbook of Chemistry and Physics is dependent on the efforts of many contributors
throughout the world. The list of current contributors follows this Preface. The new table of
Physical Constants of Organic Compounds could not have been completed without the help of
Dr. Fiona Macdonald, who oversaw the structure drawing and checked names and formulas.
Thanks are also due to Janice Shackleton, Trupti Desai, Nazila Kamaly, Matt Griffiths, and
Lawrence Braschi, who participated in drawing the structures.
