Allyl Chloride

CAS RN: 107-05-1

Volatilization

The Henry's Law constant for allyl chloride is estimated as 1.10X10-2 atm-cu m/mole(SRC) derived from its vapor pressure, 368 mm Hg(1), and water solubility, 337 mg/L(2). This Henry's Law constant indicates that allyl chloride is expected to volatilize rapidly 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 3 hours(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 3 days(SRC). Allyl chloride's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of allyl chloride from dry soil surfaces may exist(SRC) based upon its vapor pressure(1).
