    摘要： The present invention relates to a process for manufacturing a bis(chlorosulfonyl)imide (HCSI) of ultra-pure (UP) grade with a purity of at least 99.0 mol.% with respect to the total number of moles of HCSI. In addition, the present invention relates to an HCSI of UP grade obtainable from the process, and to the use of the HCSI of UP grade for preparing a lithium bis(fluorosulfonyl)imide (LiFSI). The present invention also relates to a process for manufacturing a LiFSI comprising the preparation of an HCSI of UP grade according to the present process. The present invention relates to a composition comprising a LiFSI with a purity of at least 99.99 mol.% with respect to the total number of moles of LiFSI in the composition, and to the use of a composition comprising a LiFSI obtainable from the present process in a lithium-ion secondary battery.

    摘要： A method of producing purified bis(fluorosulfonyl) imide includes providing a liquid mixture including bis(fluorosulfonyl) imide and fluorosulfonic acid and then contacting the liquid mixture with gaseous ammonia. The gaseous ammonia reacts with the fluorosulfonic acid to produce ammonium fluorosulfate. The method further includes separating the liquid mixture from the ammonium fluorosulfate.

    摘要： Aspects of the invention relate to systems and processes for recovering methanesulfonic acid, in a purified form, from a composition additionally including sulfur trioxide. In accordance with one aspect, the invention provides a process that includes separating a feed stream comprised of hydrocarbons, methanesulfonic acid, sulfur trioxide, and optionally sulfuric acid to produce a light stream comprised of hydrocarbons and a heavy stream comprised of methanesulfonic acid and sulfur trioxide; contacting (e.g., by mixing) the heavy stream with a reactive additive capable of reacting with sulfur trioxide, under conditions effective to cause reaction of the reactive additive with the sulfur trioxide to produce a heavy reaction product having a boiling point higher than the boiling point of methanesulfonic acid; and separating the heavy stream using a distillation column to produce a distillate stream consisting essentially of methanesulfonic acid and a bottoms stream comprising the heavy reaction product.

    摘要： Dimethylamine (Me 2 NH) is reacted with sulfuryl fluoride (S0 2 F 2 ) to form at least a first phase comprising N-(fluorosulfonyl) dimethylamine (FS0 2 NMe 2 ), tetramethylsulfamide (S0 2 (NMe 2 ) 2 ), or a combination thereof. A second phase, which may include dimethylamine hydrofluoride (Me 2 NH 2 F), may be also formed and separated from the first phase. FS0 2 NMe 2 or S0 2 (NMe 2 ) 2 is then isolated from the first phase. For example, the first phase may be a liquid phase, and FS02NMe2 and S0 2 (NMe 2 ) 2 are separated by distillation, optionally under reduced pressure.

    摘要： The invention relates to a method for producing salts of acrylamido-2-methylpropane sulfonic acid (A), comprising the following steps: a) producing a solution of a contaminated salt of acrylamido-2-methylpropane sulfonic acid (A) in a water-free, organic solvent (L) using at least one basic component (B) selected from the group comprising alkali metal oxides, alkaline-earth metal oxides, alkali hydroxides, alkaline-earth metal hydroxides, and amines of general formula (I) NRa Rb Rc (I), wherein the groups Ra, Rb, and Rc mean the following independently of each other: hydrogen, C1-C4 alkyl, hydroxy C1-C4 alkyl, or C1-C4 alkoxy, wherein the molar ratio of compound (A) to basic component (B) is preferably 1:1 to 1:3; b) optionally partially removing the organic solvent (L) at a pressure in the range of 0.001 to 2 bar (abs); c) recovering the dissolved salt of compound (A) by crystallization or precipitation, by changing the temperature and/or the pressure and/or the concentration of the salt in the solution; d) optionally drying the purified salt of acrylamido-2-methylpropane sulfonic acid (A). Said method according to the invention leads to salts that are poor in byproduct and especially suitable for polymerization.
