Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
OECD 113 - screening test for thermal stability
Qualifier:
according to guideline
Guideline:
other: OECD 113
GLP compliance:
no
Type of method:
differential scanning calorimetry
Boiling pt.:
ca. 255 °C
Atm. press.:
ca. 1 013 mBar
Decomposition:
yes
Decomp. temp.:
ca. 281 °C
Remarks on result:
other: the substance as heated at a temperature > 200°C starts to change color (from pale yellow to red-orange) and viscosity.The substance is thermally unstable

Result:

 Measurement  Initial boiling point °C  Decomposition °C
 1st run  262  280
 2nd run  249  283
 Average  255  281
Conclusions:
The substance over 200 °C shows the tendence to degradation (variation of physical properties) and an estimated boiling point has been determined by DSC at 255°C. At the same time the DSC allows to see a decomposition temperature at 281°C at atmospheric pressure.
Executive summary:

The substance (Z)-9-octadecen-1-ol ethoxylated has an estimated boiling point of 255 °C and an estimated decomposition temperature of 281 °C at 101325 Pa.

Description of key information

The substance has an estimated boiling point of 255 °C and an estimated decomposition temperature of 281 °C at 101325 Pa (OECD 113).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
255 °C

Additional information

The substance over 200 °C shows the tendency to degradation (variation of physical properties). An estimated boiling point has been determined by DSC at 255 °C. At the same time the DSC allows to see a decomposition temperature at 281 °C at atmospheric pressure.
