摘要:The invention relates to a new process for the synthesis of fluorinated conductive salts for lithium ion batteries (Li-ion batteries). The said fluorinated conductive lithium ion (Li-ion) battery salts of interest in the framework of the present inventions synthesis process, for example, are Li-ion salts such as LiFSI (lithium bis-(fluoromethanesulfonlyl) imide), LiTFSI (lithium bis-(trifluormethanesulfonlyl) imide), and LiTFSFI (lithium trifluoromethanesulfonylfluorosulfonyl imide), with the formulas as displayed in the Table I herein below. LiFSI, LiTFSI and LiFSTFSI are the most promising conducting salts for Lithium ion batteries and essential for future electromobility.

摘要:Disclosed are ultrafast flow synthesis of functionalized sulfonyl fluorides and subsequent SuFEx connections via lithiated chemistry. In detail, a method of synthesizing an ortho-functionalized benzenesulfonyl fluoride derivative, the method comprises (a) reacting a benzenesulfonyl fluoride derivative represented by structural formula 1 with an organolithium represented by structural formula 2, thus synthesizing an intermediate represented by structural formula 3 in reaction scheme 1 and (b) reacting the intermediate with an electrophile, thus synthesizing a compound represented by structural formula 4 or a compound represented by structural formula 4′. The present disclosure enables the synthesis of several functionalized sulfonyl fluorides within a few seconds under mild temperature conditions in addition to the chemistry of Sulfonyl Fluoride Exchange (SuFEx), which is a next-generation click chemistry, so that sulfonyl fluoride, the main reactant of the SuFEx reaction, can be efficiently secured.

摘要:In method for catalytic synthesis of crude ethylene sulfate, a sulfur trioxide solution is prepared by dissolving sulfur trioxide with a solution A, an ethylene oxide solution is prepared by mixing a solution B with ethylene oxide, a catalyst is added to the sulfur trioxide solution and mixing them to obtain a mixed solution C, the ethylene oxide solution and the mixed solution C are pre-cooled, and then introduced into a set of microchannel reactors for a real-time reaction to obtain a mixed solution containing crude ethylene sulfate, and then a post-treatment process is carried out to obtain crude ethylene sulfate. With the process, the reaction selectivity is good, and a microchannel reaction can accurately control the reaction energy level due to its rapid mixing and timely heat transfer, which greatly reduces the safety risk and effectively avoids the occurrence of side reactions.
