The Henry's Law constant for 1-methyl-2-pyrrolidone is 3.20X10-9 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 1-methyl-2-pyrrolidone is expected to be essentially nonvolatile from water surfaces(2). 1-Methyl-2-pyrrolidone's Henry's Law constant indicates that volatilization from moist soil surfaces may not occur(SRC). 1-Methyl-2-pyrrolidone is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.345 mm Hg(3).

The Koc of 1-methyl-2-pyrrolidone is estimated as 5(SRC), using a log Kow of -0.38(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-methyl-2-pyrrolidone is expected to have very high mobility in soil. 1-Methyl-2-pyrrolidinone had Rf values of 0.74, 0.65, 0.67, and 1.0 in silt, loam, clay and sand, respectively, in laboratory soil thin layer chromatography (TLC) experiments(4) which is consistent with significant mobility in soil(SRC).

InChI=1/C4H7NO/c6-4-2-1-3-5-4/h1-3H2,(H,5,6

The Henry's Law constant for 2-pyrrolidone is estimated as 1.06X10-9 atm-cu m/mole(SRC) from its vapor pressure, 9.49X10-3 mm Hg(1), and miscibility in water(2). This Henry's Law constant indicates that 2-pyrrolidone is expected to be essentially nonvolatile from water surfaces(3). 2-Pyrrolidone's estimated Henry's Law constant(1,2) indicates that volatilization from moist soil surfaces will not occur(SRC). 2-Pyrrolidone is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 9.49X10-3 mm Hg(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2-pyrrolidone can be estimated to be about 17(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-pyrrolidone is expected to have very high mobility in soil.

The Henry's Law constant for caprolactam is estimated as 5.4X10-11 atm-cu m/mole(SRC), calculated from its vapor pressure, 1.9X10-3 mm Hg at 25 deg C(1), and water solubility, 5.25X10+6 mg/l(2). This Henry's Law constant indicates that caprolactam is expected to be essentially nonvolatile from water surfaces(3). Caprolactam's estimated Henry's Law constant indicates that volatilization from moist soil surfaces will not occur(SRC). Caprolactam is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for caprolactam is estimated to be 57(SRC). According to a classification scheme(2), this estimated Koc value suggests that caprolactam is expected to have high mobility in soil.
