NIST
Standard Reference Database 87
NIST/TRC
Vapor Pressure Database
The NIST/TRC
Vapor Pressure package contains: a data file, several index files,
help files and a user interface program. The software calculates vapor
pressures using the Antoine equation or the extended Antoine equation
and displays tables for approximately 6,000 pure compounds. Users
can select the compound by name, partial name, formula or CAS Registry
Number; the user also may specify the range of temperature or pressure
and increments. The program identifies all compounds in the database
with vapor pressures in a specified range at a specified temperature.
Compound information
can be entered from batch files and the points can be calculated at
a specified pressure for identified compounds. Data are available
for vapor above both liquids and solids over a range determined by
the availability of experimental data. Extrapolations beyond the range
of experimental data are permitted. Literature sources of the Antoine
constants and the uncertainties for the data, ranging from 0.1 percent
to 5 percent, are given.
The base units
are Kelvin and kilopascal. Alternate units for temperature include:
Celsius, Fahrenheit, and Rankine. Alternate pressure units include:
bar, pascals, mm Hg, psi, inches of Hg, and kg per cm2 . The database
contains molecular formulas and up to six alternate names. All information
displayed, including results of calculations, can be reviewed, saved
to a file, or printed. The Vapor Pressure Database is updated on a
regular basis. These updates contain the most recent TRC evaluation,
newly published data, and additional features.
System
Requirements: TRCVP runs under DOS and Windows. An IBM
PC-compatible computer with DOS 2.0 or higher is required. The program
must be installed on a hard disk and requires approximately 2.5 MB.
The package comes with installation programs for either Windows or
DOS
