Description of key information

The densities of the butenes category members were reported to range from 0.555 to 0.616 g cm3. This range was 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 density of the butenes category therefore ranges from 0.555 to 0.616 g/cm3.

The density of 2-methylpropene is 0.59 (CRC, 2008). The density of 2-butene ranges from 0.588 - 0.616 g/cm³ (CRC, 2008). The density of but-1-ene is 0.588 (CRC, 2008).
