Koc values for members of the diphenylmethane category were calculated
by a reliable QSAR model.
Benzyltoluene is a slightly water
soluble, non-polar organic substance.
As a very hydrophobic substance,
supported by its measured Kow of 4.87 - 4.94, it is expected that
Benzyltoluene would strongly adsorb to organic matter in soil to an
This is conﬁrmed by the calculated KOC
values of 4.167 (MCI method) and 3.9572 (log Kow method).Calculated
values for adsorption coefficient log Koc of the other members of the
diphenylmethane category range from 4.2 to 4.9 the fact of which again
clearly indicates the very close similarity of all of its members. For
1,1 -DPE the measured log Koc is 3.64.
According to the EPI SUITE User's
Guide, the MCI methodology is somewhat more accurate than the Log Kow
methodology, although both methods yield good results.
No further testing is required.
