Abstract

Abstract The effects of the concentrations of LiCl, NaCl, KCl, CsCl, Na 2 CO 3 and BaCl 2 on the rates of reactions of hydroxide ion with ionized N-hydroxyphthalimide (NHP−) at 30 C and in H 2 O–MeCN solvents containing 10, 50, 60, 66, 70, 76 and 80%(v/v) MeCN reveal the formation of ion-pair complexes between cations of the salts, which probably exist in solvent-separated loose ion-pair forms (M n+ ⃛X k−) and NHP−. An increase in MeCN ...
