What is the purpose of adding sodium chloride to aniline?

The addition of sodium chloride to aniline serves primarily to enhance the solubility and stability of the aniline solution in various reactions, particularly in extraction processes. Sodium chloride can help to salt out aniline from an aqueous solution, promoting phase separation. Additionally, it may improve the efficiency of certain reactions by influencing the ionic strength of the solution, which can affect reaction kinetics and equilibria.
