Synthesis and Characterization of some Flourine-containing Lithium Alkyl Sulfonates: Flourinated Sulfonates and SF5-containing Sulfonates

Ullrich, Steven A. 10 March 1994 (has links)
Lithium salts of pentafluorothio alkyl sulfonic acids and perfluoroalkyl disulfonic acids were prepared for testing for possible use as polymer electrolytes. Most of these lithium salts were made from the corresponding sodium, potassium or calcium salts. Aqueous solutions of these salts were passed through polystyrene sulfonate ion exchange resin in the acid form to obtain aqueous solutions of the corresponding acids. The acids were then neutralized with lithium hydroxide using a pH meter. One salt was made by reacting the barium salt of the corresponding acid with lithium sulfate. A sulfonyl fluoride polymer (-0-CH2-C (CH20CF2CF2S02F) H-) n was reacted with lithium hydroxide to give a lithium salt as well. Owing to the great length of time required to dry these hydroscopic salts so that they might be suitable for polymer electrolyte work, alternative, water-free methods of preparation were explored. These include the reaction of lithium trimethylsilanolate with a sulfonyl fluoride, and the reaction of trimethylsilyl triflate with lithium chloride. Conductivity studies were performed on samples of these salts, and the results so far obtained from these studies are presented. Mass spectrometry, 1H, 19F and 13C nuclear magnetic resonance spectroscopy, infrared spectroscopy, and elemental analysis were used to help characterize the new lithium salts.
