ebulliometer

Key result

Atm. press.:

1 010.9 mBar

Decomposition:

yes

Decomp. temp.:

> 400 °C

Measurement

barometric pressure in mbar: 1010.9

Boiling point of sample in °C: -

Decomposition at: >400°C

Conclusions:

The boiling point of Tetracosanol was tested according to ASTM-D1120. There was no boiling point detected, because there was a decomposition at >400°C. The result is considered to be reliable.

Executive summary:

The boiling point of Tetracosanol was tested according to ASTM-D1120. There was no boiling point detected, because there was a decomposition at >400°C.

Description of key information

A commercial sample of tetracosan-1-ol was found to decompose without boiling at a temperature of >400°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

400 °C

Additional information

A decomposition temperature of >400°C was determined for the substance in accordance with a relevant test method. The result is considered to be reliable.

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.
