The Henry's Law constant for 4-methylquinoline is estimated as 7.6X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 4-methylquinoline is expected to be essentially nonvolatile from water surfaces(2). 4-Methylquinoline is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 6.4X10-3 mm Hg(3).

The Koc of 4-methylquinoline is estimated as 630(SRC), using a log Kow of 2.61(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-methylquinoline is expected to have low mobility in soil(SRC). The pKa of 4-methylquinoline is 5.67(4), indicating that this compound will partially exist in cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts(5).
