Propargyl Alcohol

CAS RN:107-19-7


The Henry's Law constant for propargyl alcohol is estimated as 1.1X10-6 atm-cu m/mole(SRC) derived from its extrapolated vapor pressure, 15.6 mm Hg(1), and water solubility, 1X10+6 mg/L (miscible)(2). This Henry's Law constant indicates that propargyl alcohol is expected to volatilize from water surfaces(3). Based on this 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)(3) is estimated as 16 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)(3) is estimated as 176 days(SRC). Propargyl alcohol's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of propargyl alcohol from dry soil surfaces may exist(SRC) based upon its extrapolated vapor pressure(1).
