Materials and methods

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.

The melting point range reported for 2 -butene is based on the cis and trans isomers.

Applicant's summary and conclusion

Conclusions:
The melting point of 2-butene ranges from -138.88 (cis) to -105.52 (trans) °C
Executive summary:

No information on the test method used is available in the handbook. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.The melting point of 2 -butene ranges from -138.88 (cis) to -105.52 (trans) °C.
