Salting out of acetylferrocene from aqueous solutions with various electrolytes

The effect of fluorides, iodides, and sulfates of a series of alkali metals and ammonia on the solubility of acetylferrocene in water at 25 degreesC w as studied to show that the nature of the anions of the electrolytes studie d stronger affects their salting out effect than the nature of the cation. By the salting out coefficient in the Sechenov equation, the salts can be a rranged in the following series: sulfates > fluorides reversible arrow chlo rides > bromides > iodides reversible arrow perchlorates reversible arrow n itrates. The latter three salts can be considered to salt in acetyferrocene . It was shown that the salting out effects of various electrolytes are bet ter compared in terms of ionic strengths rather than concentrations.
