To validate equilibrium in the partitioning vials , measurements of solute
concentration in the water phase were taken over time . The first equilibration
study was conducted as described in AN section 3 . 1 . 6 . 2 , with two minutes of

Prior to preparing the alcohol standard solution as described in 3 . 1 . 2 , a
standard solution was prepared in acetone , as as each of the alcohols is
miscible or soluble in acetone ( CRC , 2002 ) . A highly linear standard curve was
achieved .
