Boiling pt.:
194 °C
Atm. press.:
ca. 1 atm
Remarks on result:
other: measured: 380.5 °F

Measurement (repeat determination)

Observed Boiling Point: 381.0°F / 381.0°F

Barometric Pressure: 764 mm Hg / 764 mm Hg

Equilibrium Boiling Point (Corrected): 380.5°F / 380.5°F

Boiling point of octan-1-ol was determined to be 194°C at atmospheric pressure, no decomposition was reported. The result is considered to be reliable.
Executive summary:

Octan-1-ol was determined according ASTM D1120. The boiling point was determined to be 194°C at atmospheric pressure.

Description of key information

The boiling point of octan-1-ol is 194°C at 1013 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
194 °C

Additional information

A boiling point value of 194°C at 1013 hPa was determined for the substance in accordance with ASTM-D1120. The result is considered to be reliable and is selected as key study.

It is supported by values in the range ca. 194 - 195°C taken from reliable handbook sources, and a consistent result from another secondary source.

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.
