Description of key information

The boiling point of butenes range from -6.26 to 3.71 °C. This range is derived from the members of the butenes category; But-1-ene (CAS no 106 -98 -9), 2 -Butene (CAS no 107 -01 -7) and 2 -methylpropene (CAS no 115 -11 -7). 

Key value for chemical safety assessment

Additional information

The data reported is derived from the members of the butenes category and was obtained from the CRC Handbook (2008). This handbook is peer-reviewed and is considered reliable and suitable for use as a key study for this endpoint.The boiling point of butene category therefore ranges from -6.26 to 3.71 °C.

The boiling point of 2-methylpropene is -6.9˚C (CRC, 2008). The boiling points of the cis and trans isomers of 2-butene ranged from 0.88 - 3.71˚C at pressure 1013 hPa (CRC, 2008). The boiling point of but-1-ene is -6.26˚C (CRC, 2008)
