摘要：

The use of retention measurements in supercritical fluid chromatography to obtain solubilities in a supercritical fluid is discussed. In certain circumstances, retention measurements can be used to generate relatively rapidly a large body of solubility data at a particular temperature from a smaller number of measurements, obtained by more conventional methods, at either the same temperature or at least two similar temperatures. The basis of the method was tested with some published data for naphthalene and also the relatively small number of data published for fluorene, phenanthrene, and pyrene. A large body of data was then obtained for these last three compounds at 308.2, 318.2, 323.2, and 328.2 K with use of the two variations of the method. © 1990, American Chemical Society.
