The input data required for the correlations aretemptrature, density, solutendolecular weight, the solute group contributions, and the solvent basicproperties (molecular weight, critical volume, and critical pressure). The results are satisfactory.展开更多

This paper introduced the concept and features of the technique with an emphasis on three kinds of supercritical fluid crystallization techniques, i.e. rapid expansion of supercritical solutions, supercritical fluid anti-solvent and particles from gas saturated solutions Some questions and the prospect of this technique were also discussed.展开更多
