Details on results:
280ppm at room temperature

The solubility of tributyl phosphate in water at room temperature was determined according to the flask method and found to be 280 ppm. Only one saturated aqueous solution was produced, replicate analyses of the aqueous phase yielded a mean relative average deviation of 13%.

Conclusions:
Interpretation of results: moderately soluble (100-1000 mg/L)
The solubility of tributyl phosphate in water at room temperature was determined according to the flask method and found to be 280ppm; moderately soluble.
Executive summary:

The solubility of tributyl phosphate was determined according to the flask method and using gas chromatography. The solubility was determined to be 280 ppm.
