详细介绍了一种测量超临界流体中固体溶解度的新方法。该方法基于测量饱和超临界溶液溶剂-溶质的介电常数和沿不同等温线的超临界溶剂介电常数随压力的函数。我们的方法简单，绝对，易于使用，并且可以精确测量固体在超临界流体中的溶解度。萘在超临界CO2中的溶解度沿313.15、318.15和323.15 K等温线分别为12 ~ 30 MPa。
A new method for the measurement of solid solubilities in supercritical fluids is described in detail. The method is based on the measurement of the dielectric constant of the saturated supercritical solution solvent–solute and that of the supercritical solvent as a function of pressure along different isotherms. Our method is simple, absolute, easy to use, and permits precise measurement of the solubility of solids in supercritical fluids. Solubilities of naphthalene in supercritical CO2 in the pressure range 12–30 MPa are reported along the isotherms 313.15, 318.15, and 323.15 K.
