The density, viscosity, and conductivity of solutions of lithium trifluoromethanesulfonate in dimethylsulfite at 25°C have been measured. CF3SO3L1 was found to behave as a weak electrolyte, obeying the Ostwald dilution law. The equilibrium constant and equivalent conductance at infinite dilution obtained for CF3SO3L1 in DMSU were found to be 4.87 X 10 4 mol/l. and 70.2 mho cm2/equiv, respectively. The maximum specific conductance was 1.458 X 10 mho/cm. Continuing research into the feasibility of using dimethylsulfite (DMSU) as a possible nonaqueous battery solvent (13) has led to the study of the DMSU-CF3S03Li system. The deposition of Li from solutions of DMSU-CF3S03Li has already been demonstrated in this laboratory (3). The density, viscosity, conductance, and solubility of DMSU-CF3SO3L1 solutions are needed to characterize more fully this system. Measurements have been made from dilute solution to near saturation at 25°C.

atoms in a given molecule, are considered, then the ratio of the two rates corresponds to the expression Nummary Kinetics of chlorine-isotopic exchange between 1,2,3,5-tetrachloro-4,6-dinitrobenzene and lithium chloride labelled with 3 6 CI in acetone solution have been measured. The exchange is complex and consists of three simultaneous reactions -a novel situation. Allocation of the reactions to the different chlorine atoms of the aromatic molecule has been made on the basis of CNDO/2 calculations.

“…Buell (SO) has set up a classification system for nitrogen bases in petroleum dependent upon the apparent base strengths of the components according to titrations in acetonitrile and acetic anhydride solvents with perchloric acid. Acetic anhydride was also used as the solvent for the determination of the amide, e-caprolactam (8). Wimer (238) has commented on procedures permitting the direct titration of amides with perchloric acid in several solvent systems including acetic anhydride.…”
