VAPOR PRESSURE OF COMPOUNDS AND ELEMENTS

David R. Lide

This table gives vapor pressure data for about 1800 substances. In order to accommodate elements and compounds ranging from refractory to highly volatile in a single table, the temperature at which the vapor pressure reaches specified pressure values is listed. Column definitions for the table are as follows.

Column heading Definition
Name Name of substance; listed alphabetically by name
Mol. form. Molecular formula for substance
t/°C for 1 Pa Temperature at which vapor pressure reaches 1 Pa, in °C; symbol "s" following a value indicates that the substance is a solid at that temperature
t/°C for 10 Pa Temperature at which vapor pressure reaches 10 Pa, in °C; symbol "s" following a value indicates that the substance is a solid at that temperature
t/°C for 100 Pa Temperature at which vapor pressure reaches 100 Pa, in °C; symbol "s" following a value indicates that the substance is a solid at that temperature 
t/°C for 1 kPa Temperature at which vapor pressure reaches 1 kPa, in °C; symbol "s" following a value indicates that the substance is a solid at that temperature
t/°C for 10 kPa Temperature at which vapor pressure reaches 10 kPa, in °C; symbol "s" following a value indicates that the substance is a solid at that temperature
t/°C for 100 kPa Temperature at which vapor pressure reaches 100 kPa, in °C; symbol "s" following a value indicates that the substance is a solid at that temperature
Ref. Reference number

The data used in preparing the table came from a large number of sources; the main references used for each substance are indicated. Because the data were refit in most cases, values appearing in this table may not be identical with values in the source cited. The temperature entry in the 100 kPa column is close to, but not identical with, the normal boiling point (which is defined as the temperature at which the vapor pressure reaches 101.325 kPa). Although some temperatures are quoted to 0.1 °C, uncertainties of several degrees should generally be assumed.

More extensive and detailed vapor pressure data on selected important substances appear in other tables in this section of this CRC Handbook including "Vapor Pressure of Fluids at Temperatures below 300 K,"  "Vapor Pressure of Ice," and "Vapor Pressure and Other Saturation Properties of Water" in this section. "

Searching for Chemicals and Properties

The CRC Handbook of Chemistry and Physics (HBCP) contains over 700 tables in over 450 documents which may be divided into several pages, all categorised into 17 major subject areas. The search on this page works by searching the content of each page individually, much like any web search. This provides a challenge if you want to search for multiple terms and those terms exist on different pages, or if you use a synonym/abbreviation that does not exist in the document.

We use metadata to avoid some of these issues by including certain keywords invisibly behind each table. Whilst this approach works well in many situations, like any web search it relies in the terms you have entered existing in the document with the same spelling, abbreviation etc.

Since chemical compounds and their properties are immutable, a single centralised database has been created from all chemical compounds throughout HBCP. This database contains every chemical compound and over 20 of the most common physical properties collated from each of the >700 tables. What's more, the properties can be searched numerically, including range searching, and you can even search by drawing a chemical structure. A complete list of every document table in which the compound occurs is listed, and are hyperlinked to the relevant document table.

The 'Search Chemicals' page can be found by clicking the flask icon in the navigation bar at the top of this page. For more detailed information on how to use the chemical search, including adding properties, saving searches, exporting search results and more, click the help icon in to top right of this page, next to the welcome login message.

Below is an example of a chemical entry, showing its structure, physical properties and document tables in which it appears.
