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.

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.
