Abstract: 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.

Abstract: A method of producing an organopolysulfide or salt thereof is provided which includes a step of mixing an organomonosulfide or salt thereof and elemental sulfur, wherein the mixing is carried out at a temperature not greater than 95 C and in the absence of any added liquid phase for a time effective to produce the organopolysulfide or salt thereof. The described method makes possible the preparation of organopolysulfides and organopolysulfide salts without the use of solvent or catalyst.

Abstract: Metal-sulfur batteries, such as lithium-sulfur batteries, are prepared using one or more organosulfur species such as organic polysulfides and organic polythiolates as part of the liquid or gel electrolyte solution, as part of the cathode, as part of the anode (or used to treat the anode), and/or as part of a functionalized porous polymer providing an intermediate separator element.
