CAS RN:319-85-7


The Henry's Law constant for beta-hexachlorocyclohexane is 4.4X10-7 atm-cu m/mole at 23 deg C(1). This Henry's Law constant indicates that beta-hexachlorocyclohexane is expected to be essentially nonvolatile from water and moist soil surfaces(2). beta-Hexachlorocyclohexane is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 3.6X10-7 mm Hg(3).
