Sax (1986) t½ ~89 years at 25°C and pH 7 Hydrolysis as a Function of pH The half-life at 25°C was extrapolated from kinetic measurements made under aqueous alkaline conditions at temperatures of 64°C and 84°C. et al. (1996) Sabaliūnas log Kow = 0.98 Partition Coefficient Literature data (Hansch et al., 1995) Remarks The log octanol-water partition coefficient (log Kow) was calculated to be 1.38 (KOWWIN (v1.67), US EPA (2009). Hansch et al. (1995) log Koc = 1.43 Adsorption/Desorption screening test – Literature data (Sabljić, 1987) Remarks The soil adsorption coefficient was calculated to be 41.55 (log Koc = 1.62) by the MCI method and 24.65 (log Koc = 1.39) by the Kow method (KOCWIN (v2.00), US EPA (2009)). The notified chemical is expected to be highly mobile in soil. Sabljić (1987) pKa = 9.7 at 25°C Dissociation Constant The pKa value of the notified polymer (pKa = 9.7 at 25°C) was inferred from the pKa value of the hydrochloride salt of alpha-propyl-2-methyl-propioanilide, as the amidic bond of the propioanilide is similar to the amidic bond of the notified chemical. et al.
