Description of key information

Hydrolysis is not a relevant environmental abiotic degradation pathway for 1,2,3-trichloropropane.

Key value for chemical safety assessment

Additional information

Rate constants for hydrolysis of TCP have been studied experimentally (Ellington et al. 1987). The experimental rate constant for neutral reactions was 1.8 x 10-6 and that for basic reactions was 9.9 x 10-4. The half-life of the substance in water due to hydrolysis at environmentally relevant conditions that can be calculated from these rate constants is 44 years (WHO 2003) indicating that this abiotic degradation pathway is not relevant for TCP.
