Description of key information

Additional information

A hydrolysis constant of 5.0 x 10-6 per hours (pH 7-9, 25°C) with a calculated half-life of 15.8 yr, has been derived for 1,2-dichloropropane in water (MacKayet al., 1993). Therefore the substance shows a very good stability in water as it is not subject to any abiotic degradation (hydrolysis), unless in a very long time.

1,2-Dichloropropane does not have any chromophore groups that absorb wavelengths >290 nm, so direct photolysis will not be a significant fate process.
