Description of key information

The soil adsorption coefficient (Koc) for Di-n-butyl ether (CAS: 142-96-1) was estimated
using OECD Guideline 121: “Estimation of the Adsorption Coefficient (Koc) on Soil and
on Sewage Sludge using High Performance Liquid Chromatography (HPLC)”.

Key value for chemical safety assessment

Additional information

The HPLC method compares the retention time of the test substance in a defined HPLC assay to the retention times of a series of referencesubstances with known Koc values.The retention time for dibutyl ether correlated to an estimated log Koc value of 2.63.
