(Z)-9-Octadecen-1-ol ethoxylated

Boiling point

Link to relevant study record(s)

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
