SOLUBILITY OF HYDROCARBONS IN SEAWATER

Concern about pollution of the oceans has stimulated measurements of the solubility of organic compounds in seawater. This table gives the solubility of several hydrocarbons in seawater. The data are derived from a review in the IUPAC Solubility Data Series (Ref. 1).

Solubility is expressed in this table as parts per million by mass, i.e.,

S/ppm(mass) = 106 × w2 = 106 × m2/(m1 + m2)

where m1 and m2 are the masses of solvent (seawater) and solute, respectively, under saturation conditions, and w2 is the mass fraction. Because the solubilities in this table are very low, the value of S is effectively the mass of hydrocarbon in grams per 1000 kg of seawater. Column definitions for the table are as follows.

Column heading Definition
Name Hydrocarbon name
Mol. form. Molecular formula of hydrocarbon
Salinity Salinity is a standardized measure of the concentration of dissolved salts, as explained in the table “Properties of Seawater” in Section 14; salinity values in the open oceans at mid-latitude typically fall between 34 and 36
t Temperature of measurement, in °C
S Solubility, as parts per million by mass

Ref. 1 gives details of the method of measurement and an indication of the reliability of the values.

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.
