Additional information

A calculated Koc between 0.4944 to 1.0 (logKoc = -0.3016 to 0) was determined for 1,4 -butynediol using USEPA KOCWIN v. 2.0. These results indicate that 1,4 -butynediol is likely to remain in water and not adsorb to the organic portion of soils and sediments. 1,4 -Butynediol is expected to be highly mobile in soil but this movement will be mitigated by rapid biodegradation.
