Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:

Type of information:
experimental study
Adequacy of study:
key study
Study period:
Up to 2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Non-GLP, non-guideline, Information from published handbook, acceptable with restrictions.
Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.

Additional information

Data from the CRC handbook (Lide 2008) were available for the substances methane, ethane, propane, butane and isobutane. Data are also available from the Merck handbook (O’Neill 2006) for methane, ethane, propane and butane. The information is taken from reliable peer reviewed handbooks and so can be considered reliable and suitable for use for this endpoint.

The boiling point of methane is -161.48°C, ethane is -88.6°C, propane is -42.10°C, butane is -0.5°C and isobutane is -11.73°C. The mean of the boiling point values for the category is -60.9°C and this has been used to complete the 'key value for chemical safety assessment'.
