Solvent Selection Problem Formulation

Problem formulation is an important first step in solvent selection as it is necessary first to define the functions of the solvent before attempting to find suitable candidates. Each problem, characterized in terms of solvent and solute properties, needs to address a set of issues related to separation task, performance, environmental impact and problem-specific (special) considerations. The solvent selection problem is formulated in terms of a set of properties (target properties) and their values (target values). A two-step procedure, consisting of a problem identification step (identifies the solvent functions and issues that need to be addressed) and a criteria for evaluation step (selects target properties and their target) is recommended.
