Additional information

The HPLC method using soil-adsorption-reference data was applied for the determination of the adsorption coefficient (Koc) of Benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene.

The Koc and log Koc values of the major component of test substance at neutral pH were 3.0E+5 and 5.48 respectively. Multiple minor components over a large log Koc range were observed.

[LogKoc: 5.48]
