摘要：

Polythermal study of the solubility reveals that the higher solubility of acetylferrocene in water relative to that of ferrocene (-logS at 25 degrees C 1.75 and 4.16, respectively) is due to the entropy factor. The solubility of acetylferrofene at 25 degrees C is determined in aqueous 1:1 electrolytes taken in concentrations of 0.5, 1.0, 2.0, 3.0, and 4.0 M. Chlorides (LiCl, NaCl, KCl, and NH4Cl), bromides (LiBr, NaBr, and KBr), and potassium nitrate salt-out acetylferrocene from solutions in direct proportion to the electrolyte concentration. In solutions of LiClO4, NaClO4, LiNO3, and NH4NO3 (but not NaNO3) salting-in of acetylferrocene is observed (concentration dependences for these electrolytes are curvilinear).
