The partition coefficient (log Pow) of butenes ranges from 2.31 to 2.4. The data were reported for the members of the butenes category: but-1-ene (CAS 106-98-9), 2-butene (CAS 107-01-7) and 2-methylpropene (CAS 115-11-7).
handbook by Hansch et al. (1995) is critically evaluated and considered
reliable and suitable for use as a key study for this endpoint. The
partition coefficient (log Pow) of the butenes ranges from 2.31 to 2.4.
partition coefficient (log Pow) of 2-methylpropene is 2.34 (Hansch
1995). The log Pow of 2-butene ranges from 2.31 to 2.33 (Hansch 1995).
The partition coefficient (log Pow) of but-1-ene is 2.4 (Hansch
1995).The mean of the log partition coefficient values for the butenes
is 2.35 and this has been used to complete the 'key value for chemical
