Description of key information
Additional information
STABILITY:
- Terrestrial
Volatilization of diisopropylamine from moist soil surfaces is not expected to be an important fate process since the cation will not volatilize. The potential for volatilization of diisopropylamine from dry soil surfaces may exist based upon a vapor pressure of 79.4 mm Hg at 25 deg C (Daubert TE, Danner RP; Physical and Thermodynamic Properties of Pure Chemicals Data Compilation Washington, DC: Taylor and Francis (1989)).
- Aquatic
Volatilization from water surfaces is not expected to be important fate process since the protonated form is not expected to volatilize at environmental pH.
- Atmosphere
According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere (Bidleman TF; Environ Sci Technol 22: 361-367 (1988)), diisopropylamine, which has a vapor pressure of 79.4 mm Hg at 25 deg C, is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase diisopropylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 4 hours, from its rate constant of 9.7*10 -11 cm3/molecule-sec at 25 deg C (Meylan WM, Howard PH; Chemosphere 26: 2293-99 (1993)). Diisopropylamine is not expected to directly photolyze due to the lack of absorption in the environmental UV spectrum.
BIODEGRADATION:
- Biotic
Diisopropylamine (DIPA) is not considered to be ready biodegradable based on a screening biodegradation test.In addition, DIPA showed a mean elimination of 0% in an aerobic aqueous medium according to OECD 303A guideline.
- Abiotic
In relevant environmental conditions it is not expected to have substitution process occurring between amino- and hydroxyl groups. Therefore diisopropylamine is not subject to hydrolysis and is stable.
BIOACCUMULATION:
Diisopropylamine is not expected to bioaccumulate in aquatic or terrestrial organism tissues due its high water solubility and its low Log Pow.
TRANSPORT AND DISTRIBUTION:
Diisopropylamine is not expected to sorb on soil particles due its high water solubility and its low Log Koc.
