Results and discussion

Any other information on results incl. tables

Alcohol sorption coefficients showed some time dependence, reaching a plateau by 72 h. C15 was found to be an unexplained outlier. The 72 h 

results were:
        
C       12       14       15       16       18

Kd      3000±    8490±    3080±    23800    78700
          80      920      270     ±3200    ±5400

Koc     17980    50830      -    143000   471000

log Koc   4.25    4.71      -     5.15     5.67

These data (neglecting the C15) can be interpreted as a QSAR in the usual way as:

Log Koc = 0.11 + 0.77 log Kow

R2 = 0.994

The result is in line with typical QSARs of this type.
