melting point (theory) in °C:47.6 (+/-0.2)

melting point (experimental) in °C:47.7


(triple determination)

initial temperature in °C:65.0 / 65.0 / 65.0

final temperature in °C:75.0 / 75.0 / 75.0

Melting point in °C:70.5 / 70.5 / 70.3

measurement pressure:atmospheric pressure

A pour point of 71°C at 1013 hPa was determined for the substance using a relevat test method. The result is considered to be reliable.
Executive summary:

The Pour point of docosan-1 -ol was determined to be 71°C at atmospheric pressure according to OECD Guideline 102.

Description of key information

The pour point of docosan-1-ol is 71°C at 1013 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
71 °C

Additional information

A measured pour point value of 71°C at 1013 hPa was determined in accordance with OECD 102 Test Guideline.The result is considered to be reliable.

It is supported by a value of 72.5°C taken from a reliable handbook.

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

As the chain length increases, melting point increases. This is because molecular weight is higher and intermolecular forces in the substance are all higher.
