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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 log Koc was determined with 0.18.
Test method: OECD GL 121 / EC test guideline C.19 (HPLC).
Key value for chemical safety assessment
- Koc at 20 °C:
- 12.99
Additional information
The adsorption coefficient of methyl acetate was determined by HPLC method. The capacity factors k' were calculated. The log k' value were plotted against the respective log Koc values of the reference substances. The log Koc value of methyl acetate was calculated by means of the regression line equation resulting in 0.18. On the basis of this value the Koc is calculated as 12.99 l/kg.
Henry's law constant was determined to be 6.43 Pa m³/mol at 20 °C.
The atmosphere and the hydrosphere are the target compartments for methyl acetate in the environment. The following theoretical distribution in the environment results for methyl acetate:
Air 69.3 %
Water 30.7 %
Soil 0.0 %
Sediment 0.0 %
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.
