Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 report concluded a boiling point of 201.2°C.
The registrant (manufacturer) considered that this interpretation of the DSC endotherm at this temperature was incorrect. Even Tetrahydrofurfuryl acrylate, one of the smallest (MW = 156) and most volatile substances in this family, has a slightly higher boiling point (206.5 °C). It is therefore chemically impossible that the test substance with very high MW (all components >500) boils at 201.2°C. As the test substance is an amine-modified acrylate, a more likely interpretation for the endotherm seen at 201.2°C is thermal decomposition of the amine-acrylate bonds.
Therefore this value is not kept as key value.
Key value for chemical safety assessment
Additional information
An endotherm seen at 201.2°C was not considered to correspond to boiling, but to thermal decomposition.
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.
