Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The value was derived from a recognised source of physico-chemical data.
Principles of method if other than guideline:
No details are available on the guideline used to determine this result.
GLP compliance:
not specified
Melting / freezing pt.:
49.3 °C
Atm. press.:
other: See Remark
Remarks on result:
other: The atmospheric pressure at which this result was determined is not stated but it is consistent with expected properties at standard pressure.
Melting / freezing pt.:
50 °C
Remarks on result:
other: The atmospheric pressure at which this result was determined is not stated but it is consistent with expected properties at standard pressure. This value was taken from an older edition of the Handbook (1990)
Conclusions:
A melting point value of 49.3ºC is reported in a handbook of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.
Endpoint:

Measurement parameters:

Thermometer range: 32 to 127 °C

Sample volume: 30 mL

Measurement:

Pour point: 51 °C / 51 °C (duplicate measurement at two different days)

Conclusions:
Pour point of Hexadecan-1-ol: 51 °C at atmospheric pressure
Executive summary:

The Pour Point of Hexadecan-1 -ol was determined to be 51 °C at atmospheric pressure according to ASTM-D97 Standard Test Method for Pour Point of Petroleum Products.

Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: This information was obtained from the public IUCLID 2000 CD-ROM. Further review of the original source to reassign the reliability would not alter the overall conclusions concerning this endpoint. A source of higher reliability is available.
Melting / freezing pt.:
49 °C

Description of key information

The melting point of hexadecan-1-ol is 51°C.

Key value for chemical safety assessment

Additional information

The melting point of 51°C was determined in a reliable study.

It is supported by a value of 49.3°C taken from a reliable handbook, and various consistent results from other reference sources of non-assignable reliability.

 

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

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