摘要

The conductance of lithium and cesium dinonylnaphthalene sulfonates was measured in a variety of solvents at 35C. Linear Shedlovsky plots indicating a simple ion/ion-pair equilibrium were obtained for the following systems: LiDNNS-methanol, LiDNNS-ethanol, LiDNNS-nbutanol, and CsDNNS-acetone. Comparisons of dissociation constants from these plots with published data for the corresponding halides show an increased tendency toward association for the sulfonates, the dissociation constants being smaller by an order of magnitude than for the halide salts. Association beyond ion-pairs was indicated by the nonlinear Shedlovsky plots observed for the following systems: CsDNNS-ethanol, CsDNNS-nbutanol, CsDNNS-methylisobutyl ketone, CsDNNSnitromethane, CsDNNS-1-nitropropane, LiDNNS-nitroethane, LiDNNS-1-nitropropane, LiDNNS-acetone, and LiDNNSmethylisobutyl ketone.
