Introduction
The boiling point of the test substance was determined using a test method based on EU Method A.2 (Boiling Temperature).
Method
The distillation method was used. 60 ml of test substance is placed in the flask. The condenser water is turned on and heat applied by means of an electric heater at such rate that the sample is brought to its boiling point within 15 min. The sample is heat strongly until boiling is reached and then the heat input is reduced slowly until the required reflux rate is obtained. The rate of reflux is adjusted over the next 10 min period to 1 to 2 drops of reflux per second. To obtain accurate results, the specified reflux rate is observed and maintained for 2 min before reading the temperature.
Three runs are undertaken and the mean of the results assigned as the boiling point value

Additional information
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).
