Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 streams in this category is in the range 99.6 to 265°C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 172 °C
Additional information
Proprietary studies were available from GKA Competence Centre Analytics (2008) for the stream 68477-39-4 (151°C) and from Chilworth Technology Limited (2009) for the stream 64741-98-6 (99.6°C). These studies were in accordance with a standard guideline and are considered reliable for assessment. The data from these studies will be read across to other members of the category.
RÜTGERS Germany GmbH, Analytisches Zentrallabor (AZL) (2010) provided data for the stream 64742-94-5 (193°C to 265°C) via a signed Certificate of Analysis. The data provided details on the method used and are considered adequate for assessment.
The mean of the boiling point values for the category is 172°C and this has been used to complete the 'key value for chemical safety assessment'.
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).
