Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Experimental studies at high temperatures are waived due to polymerisation.
In a non-GLP study using the static method, vapour pressure was concluded as 319 Pa at 20.0°C. The study is disregarded due to major flaws (see study summary conclusion), and in particular the result is inconsistent with experimental vapour pressue of raw material Tetrahydrofurfuryl alcohol (CAS 97-99-4: 107 Pa at 25°C in MPBPWIN v1.4 training set): the acrylate cannot be 3 times more volatile than its alcohol.
The QSAR MPBPWIN v1.43 predicts uncorrected vapour pressure estimates: 34.7, 104 and 376 Pa; 1.87, 6.92 and 20.5 kPa at 25, 40, 60, 90, 120 and 150°C, resp. By considering analogous data (experimental VP of the alcohol, and experimental VP difference between an acrylate of the same MW and its alcohol), these are corrected upwards by a factor of 3.43 into: 119 and 356 Pa; 1.29, 6.41, 23.7 and 70.3 kPa at 25, 40, 60, 90, 120 and 150°C, resp.
The corrected QSAR values are acceptable for exposure assessment and classification and labelling.

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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
