Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Migrated dataset;

RS-Freetext:
Based on the model calculations (Mackay level I, v.2.11), the target  compartment for the environmental distribution of 1,4-dichlorobut-2-ene is the air.
Water:          1.77 %
Air:           98.12 %
Soil:           0.021 %
Sediment:       0.021 %
Susp. Sediment: 1.38E-04 %
Biota (fish):   1.34E-05 %
Aerosol:        7.41E-06 %
Although data of several studies with pure isomers have been combined, all Mackay calculations indicate that during equilibrium most of the  mixture will be in the gas phase, followed by water, and further by soil

and sediment
