EC number: 203-529-7
CAS number: 107-88-0
Adsorption / desorption
In accordance with column 2 of REACH Annexes VIII, IX and X, an
adsorption/desorption screening study and further studies do not need to
be conducted, because the substance has a low potential for adsorption
due to a low octanol-water partition coefficient, and the substance and
its relevant degradation products decompose rapidly.
Based on a calculated Koc of 1 (PCKoc v1.66), 1,3 -butanediol is
expected to have high mobility in soil (ECT, 2008).
Henry's Law constant / Other distribution data
The Henry's Law constant (HLC) was estimated to be 0.0233 Pa*m³/mol at
25 °C. Taking this value, volatilization half-lives of 101 and 1102 days
were estimated by EPIWIN v3.20 for a model river and a model lake,
respectively (ECT, 2008)
