Atm. press.:
ca. 101.3 hPa
Remarks on result:
other: Temperature range: 157-230 °C


Under the study conditions, the boiling point of the test substance was determined to be 204°C.
Executive summary:

A study was conducted to determine the boiling point of the test substance, C12-18 DAQ (99.6% active), according to the method equivalent or similar to OECD guideline 103. The analysis was performed with differential scanning calorimetry on a Mettler DSC 1 under nitrogen atmosphere (20 mL/min). The temperature range of -30-300 °C (5°C/min) was used. 12.7 mg of test substance sample was placed in a 40 µL aluminium cup for analysis. Under the study conditions, the boiling point of the test substance was determined to be 204°C (Ulama & Karlsson, 2010).

Description of key information

The boiling point of the test substance was determined using differential scanning calorimetry, according to a method similar to OECD Guideline 103 (Ulama & Karlsson, 2010).  

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
204 °C
