The solubility ofdichlorobis(triphenylphosphine)nickel(II) insupercritical carbon dioxide was determinedusing a dynamic method. Solubility isotherms were obtained at(308, 318, and 328) K in the pressurerange (10.8 to 27.9) MPa. Solubilities increased linearly withincreasing density at constant temperatureand increased with increasing temperature at constantdensity.
