When User-Supplied Solubility Data are supplied for SLE K-values, data may be missing for one or more of the binary pairs. Three options are provided for filling in missing values of xij.
The default option is to fill in missing values with xij as calculated by the van't Hoff equation.
The second option is to assume that the solute is completely dissolved. The third option causes the missing solvent or solvents to be ignored in the solubility calculation.
More information is available in the topic "Fill Options for Solubility Data" under "Solid-Liquid Equilibria" in Chapter 2, Volume 1, of the PRO/II Reference Manual.
