The Henry's Law constant for diethyl malonate is estimated as 2.0X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 0.19 mm Hg(1), and water solubility, 2.0X10+4 mg/L(2). This Henry's Law constant indicates that diethyl malonate 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 23 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 173 days(SRC). Diethyl malonate's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). In chemical stimulant studies simulating chemical warfare agents, diethyl malonate deposited to dry soil and foliar surfaces is rapidly lost through volatilization processes with observed half-lives on soil of about 2 hours (fast) to 5-16 hours (residual material)(4); foliar half-lives ranged from 1 to 242 hours(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of diethyl malonate can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethyl malonate is expected to have very high mobility in soil(SRC).
