| Volatilization | The Henry's Law constant for trans-crotonic acid is estimated as 2.4X10-7 atm-cu m/mole(SRC) from a vapor pressure of 0.18 mm Hg(1) and a measured water solubility of 8.6X10+4 mg/l(2). This value indicates that trans-crotonic acid will be essentially nonvolatile from water surfaces(3,SRC). trans-Crotonic acid's Henry's Law constant(1,2,SRC) indicates that volatilization from moist soil surfaces is not expected to occur(SRC).

| Soil Adsorption | The Koc of crotonic acid is estimated as approximately 59(SRC), using a measured log Kow of 0.72(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that crotonic acid is expected to have high mobility in soil(SRC).
