CAS RN:107-15-3


Ethylenediamine has a Henry's Law constant of 1.73X10-9 atm-cu m/mole(1). This Henry's Law constant indicates that ethylenediamine is expected to be essentially nonvolatile from water surfaces(2). As ethylenediamine has two primary amine groups, at the pH range found in most environmental waters, it is expected to be partially protonated; the dissociated form will not volatilize. The Henry's Law constant of ethylenediamine(1) also indicates that volatilization from moist soil surfaces should not occur(SRC). The potential for volatilization of ethylenediamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 12.1 mm Hg(3).
