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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
>300 °C, decomposition probable
Key value for chemical safety assessment
Additional information
The boiling point was evaluated based on the available information about the boiling point of fatty acid esters and its correlation with molecular mass and chain length. Fatty acid esters such as CAS 70913-98-3 of molecular weight >300 amu and a β-hydrogen in the alcohol chain (≥ C3) have a boiling point > 300 °C and decompose before boiling. Measured boiling points of fatty acids short chain methyl ester (SCAE ME) are in the range: 338°C for C16 ME (MW = 270,4558) to 352 °C for C18 ME (MW = 298,5095) and prove that the boiling point increases with the increase of molecular weight / chain length. It is concluded that the the boiling point measurement does not need to be performed as the substance decomposes before boiling. For the chemical safety assessment the conservative value >300 °C is chosen.
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.
