A trend of increasing partition coefficient with increasing carbon number is seen for category members.
coefficient increases with increasing carbon number across the category,
with a very similar trend for both the alpha olefins and olefins. Data
is available for category members with carbon numbers of C6 to C24. Two
QSAR have been used to support the experimental data and to fill data
smallest category members have log Kow above 3. The log Kow rises to
>6.5 by around C10 -C12. Experimental methods to determine partition
coefficient are unable to determine partition coefficients above this.
Therefore, although some experimental data is available for category
members with higher carbon number the results are expressed as unbounded
values or >6.5, >8 etc. The QSAR values indicate that partition
coefficient continues to increase with carbon number, reaching log Kow
>10 by around C20.
