Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The boiling point of the test item was determined to be in range from 236 to 238 °C at 1013.25 hPa.
Key value for chemical safety assessment
Additional information
A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 and EPA OCSPP test guideline 830.7220 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 11 – 13 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. The substance is a liquid at ambient conditions. Therefore the crucibles were cooled down from ambient temperature to -100 °C with a constant cooling rate of 0.25 K/min under an inert atmosphere. After a waiting period of 30 min at -100 °C, the temperature was increased up to 500 °C at a constant heating rate of 10 K/min. Between approx. 160 – 250 °C, an endothermic effect (boiling) was detected. The correction of the boiling temperature to standard pressure was performed according to H.N. Hass and R.F. Newton. A boiling range of the test item of 236 – 238 °C corrected to normal atmospheric pressure was determined. No further thermal effects were observed up to the maximum test temperature of 500 °C. No observations were made which cause doubt on the validity of the outcome of the study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
