EU Risk Assessment on the major component of C4 Hydrocarbons: 1,3-Butadiene:

The water solubility of 1,3 -butadiene is quoted as ranging from 0.5 g/L to 0.735 g/L at 20 °C (consolidated IUCLID entry).

The value of 0.735 g/L is taken from McAuliffe (1966), who measured the water solubility using gas-liquid chromatography. pH of the solution was not reported.

Applicant's summary and conclusion

Executive summary:

The solubility of the major component of C4 Hydrocarbons: 1,3 -butadiene was reported in EU Risk Assessment on 1,3-Butadiene (2002) to be in range of 0.5 g/L to 0.735 g/L at 20 °C.
