Executive summary:

Undecanol, branched and linear is measured according to ASTM 537 -07. The boiling point is determind to be 238.4 °C at atmospheric pressure.

Description of key information

The boiling point of undecan-1-ol is 247°C based on a reliable study conducted in accordance with ASTM 537-07 method.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
247 °C

Additional information

The boiling point of 247°C was determined in a reliable study.

It is supported by a value of 243°C taken from a reliable handbook, and a consistent result from another reference source. Other data available were measured at reduced pressure and therefore of little value for the REACH data set.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols:

As chain length increases, boiling point increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher. There is some evidence for decomposition before boiling for the longest chain alcohols in this group.
