Volatilization | The Henry's Law constant for 2-phenylethylamine is estimated as 8.1X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 2-phenylethylamine expected to volatilize slowly from water surfaces(2). Based on this estimated Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 50 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 365 days(SRC).

Soil Adsorption | The soil/water distribution coefficient (Kd) for 2-phenylethylamine was experimentally determined to be 2.1 in a silty-clay loam soil with an organic carbon content of 1.7%(1), which corresponds to a Koc value of 120(SRC). According to a classification scheme(2), this Koc value suggests that 2-phenylethylamine is expected to have high mobility in soil. The pKa of 2-phenylethylamine is 9.83(3), indicating that this compound will primarily exist in cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts(4); however, aliphatic cations are more weakly sorbed than those associated with aromatic ring systems(1).
