Acetonitrile-rich phase
Method/Apparatus/Procedure:
The analytical method was used. Each two-phase mixture in a 70 mL equilibrium cell was stirred intensely for 2 h and then was allowed to settle for 2 h at 25.00 °C in a thermostated water bath. Two liquid samples in equilibrium were withdrawn with Hamilton syringes and were analyzed by means of a gas chromatograph and an electronic integrator.
