Boiling point at 101 325 Pa:
-60.9 °C

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'.
