METHOD FOR PRODUCING DERIVATIVE OF ORGANIC SUBSTANCE AND METHOD FOR ANALYZING SAMPLE CONTAINING ORGANIC SUBSTANCE
Derivatives of an organic substance containing one or more groups selected from the group consisting of sulfanyl, selanyl and sulfino may be produced by reacting an organic substance containing one or more groups selected from the group consisting of sulfanyl, selanyl and sulfino with an olefin compound containing an ethylene structure having at least two electron-withdrawing groups except halogen atoms under an acidic condition to form a derivative of the organic substance
NON-AQUEOUS ELECTROLYTE, POWER STORAGE DEVICE USING SAME, AND LITHIUM SALT USED FOR SAME
A nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing a lithium salt having a specific α,β-dihydroxy carboxylic acid ester structure, phosphono hydroxy carboxylic acid structure, alkoxycarbonyl hydroxy carboxylic acid structure, or formyloxy structure; an energy storage device using the nonaqueous electrolytic solution; and a lithium salt used for the nonaqueous electrolytic solution. This nonaqueous electrolytic solution makes it possible not only to improve the electrochemical characteristics when the energy storage device is used at a high temperature and a high voltage and to improve the capacity retention rate after high-voltage and high-temperature storage, but also to suppress gas generation.
