We report the use of the unimolecular, spontaneous decarboxylation of 6-nitrobenzisoxazole-3-carboxylate, 6-NBIC, as kinetic probe to investigate properties of aqueous solutions of a series of ILs, 1-alkyl-3-methyl imidazolium derivatives. The ILs are denoted as [Cnmim][X], where n indicates the number of carbon atoms in 1-alkyl chain. We studied [C4mim][X], with X = Cl-, Br- and BF4-, and the surface active ILs, SAILs, [C12mim][Cl], [C12mim][Br], and [C16mim][Br]. We observed a steep increase of values of kobs after a certain salt concentration for all the systems used. Electrical conductivity of various aqueous systems were measured, in an attempt to rationalize the kinetic effects.

Abstract
We report the use of the unimolecular, spontaneous decarboxylation of 6-nitrobenzisoxazole-3-carboxylate, 6-NBIC, as kinetic probe to investigate properties of aqueous solutions of a series of ILs, 1-alkyl-3-methyl imidazolium derivatives. The ILs are denoted as [Cnmim][X], where n indicates the number of carbon atoms in 1-alkyl chain. We studied [C4mim][X], with X = Cl-, Br- and BF4-, and the surface active ILs, SAILs, [C12mim][Cl], [C12mim][Br], and [C16mim][Br]. We observed a steep increase of values of kobs after a certain salt concentration for all the systems used. Electrical conductivity of various aqueous systems were measured, in an attempt to rationalize the kinetic effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
