completely miscible

Triplicate: saturated solutions were agitated at 30 °C for the time indicated in the table. 

Afterwards, each flask was allowed to equilibrate for 24 h at 20 °C.

After centrifugation and filtration (0.45 µm filter) the content of the substance in the aqueous phase was determined by HPLC with UV-detector.
