Abstract

Using the methods of circulation distillation and Rayleigh distillation, the liquid-vapor separation coefficients in the systems tetrakis(trifluorophosphine) nickel – dichloromethane and tetrakis(trifluorophosphine) nickel – pentane at 298 K were determined. For the tetrakis(trifluorophosphine) nickel – dichloromethane system the values αcir and αeff are 4.9 ± 0.8 and 11.7, accordingly, for the tetrakis(trifluorophosphine) nickel – pentane system the values are 4.2 ± 0.4 and 20.3, accordingly. The results obtained are consistent with the results of a theoretical assessment of the values αcir and αeff of the vapor-liquid separation coefficient according to Raoult’s law.
