Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Hydrolysis is an important degradation reaction in the environment, for example in surface, ground, fog and pore water. Two main reaction mechanisms can be stated for a hydrolytic reaction Nucleophilic Substitution (SN1 and SN2) and Addition – Elimination. Important classes reacting under hydrolytical cleavage are for instance esters, amides, epoxides, carbamates and halogenated aliphates. 1,7-Octadiene is a simple hydrocarbon which does not bear any of these chemical groups and therefore is not expected to undergo hydrolysis under environmental relevant conditions (e.g. pH value ranging from 4 to 9).
