Measured Range

The conventional activity of chloride ions was measured by an ion-selective electrode at 25 °C in aqueous solutions of benflurone, i.e. 5-(2-(N,N-dimethylamino)ethoxy)-7-oxo-7H-benzo(c)fluorene hydrochloride, without or with additions of KCl. These results suggest a gradual association of benflurone; the formation of a hetero-associate, (BH+)2Cl-, followed by higher associates was evaluated in the measured range up to 0.1 mol l-1.
