ENTHALPY OF FUSION

This table lists the molar enthalpy (heat) of fusion, ΔfusH, for over 1100 inorganic and organic compounds. All values refer to the enthalpy change at equilibrium between the liquid phase and the most stable solid phase at the phase transition temperature. Most values of ΔfusH are given at the normal melting point tm; see column definition table for details.  Temperatures are given on the ITS–90 scale.

Column definitions for the table are as follows.

Column heading Definition
Name Name of substance, either an IUPAC systematic name or, in the case of drugs and other complex compounds, a common synonym; listed alphabetically
Mol. form. Molecular formula in the Hill convention
tmp Normal melting point; a “tp” following the entry in the melting point column indicates a triple-point temperature, where the solid, liquid, and gas phases are in equilibrium; all temperatures are in °C; a few entries have the triple-point pressure indicated; (dec) = decomposes 
ΔfusH Molar enthalpy of fusion, in units kJ mol-1

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.
