Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Executive summary:
In accordance with column 2 of EC 1907/2006 Annex VII the boiling point measurement does not need to be performed as the substance decomposes before boiling. Boiling point is a property which shows a correlation with increasing molecular weight / chain length and increasing boiling point. Measured boiling points of fatty acids short chain methyl ester (SCAE ME) prove this correlation, so the highest measured boiling point for C16 ME (MW = 270,4558) is 338°C, for C18 ME (MW = 298,5095) is 352 °C. Blake et al. (J. Chem. Eng. Data, 1961, 6, 87-98) show for esters of long chain acids that all esters with β-hydrogen atoms in the alcohol (i.e. alcohols with C3, e.g. propanol) decompose in the range between 262 and 283 °C. Conclusion: Esters of fatty acids esterified with alcohols ≥ C3 and having a molecular weight exceeding 300 amu have a boiling point > 300 °C and decompose before boiling.

There are no values given for pressure. No information is given on decomposition/sublimation temperature.
Description of key information
> 300 °C, decomposition probable
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 300 °C
Additional information
The study reporting an experimental b.p. of only 75 °C is assumed to be performed at reduced pressure (pressure not reported) as the individual boiling points of the acid and alcohol components of the ester at atmospheric pressure already exceed 200 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
