Reference
A defined value for the boiling point of test item Alcohols, C10 -12, Ethoxylated (EO < 2.5) could not be determined based on the effects observed in the DSC experiments. The DSC curve, i.e. the peak shape and peak magnitute, indicates boiling and/or thermal decomposition starting at ca. 187 °C (at 1036 hPa).
190 °C (from first measurement)
185 °C (from second measurement)
187 °C (from third measurement)
192 °C (from fourth measurement)
182 °C (from fifth measurement)
Description of key information
boiling and/or thermal decomposition starting at ca. 187 °C at 1036 hPa (OECD 103, DSC)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 187 °C
Additional information
The boiling point of the substance was determined with differential scanning calorimetry according to OECD Guideline 103. The DSC curve shows various effects attributed to boiling and/or thermal decomposition starting at ca. 187 °C (at 1036 hPa).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
