Description of key information

The substance 1-chlorobutane is transformed in air by indirect photolysis with a calculated half-life of 10.7 days.

Key value for chemical safety assessment

Half-life in air:
10.7 d
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

A half-life of 10.7 days for indirect photolysis of 1-chlorobutane was calculated using AOP version 1.53 (Syracuse Research Centre) as was published by Atkinson (1987). The rate constant of indirect photolysis was calculated at 1.5*E-12 cm3molecule-1 s-1 (which is equivalent to 1.3E-07).
