Additional information

Henry's Law constant of tributyl acetylcitrate was calculated using EPIWIN (v4.0), HENRYWIN (v3.20). The calculation of Henry's Law constant according to the equation H=vp/ws yielded a value of 4.434 Pa x m³/mole using a measured water solubility of 4.49 mg/L and a vapour pressure of 0.000371 mm Hg. Based on the result, tributyl acetylcitrate can be considered to be moderately volatile from aqueous solution.
