Patent number: 8863479Abstract: A container containing a fluorinated organic carbonate and a gas atmosphere which contains a cover gas selected from the group consisting of a noble gas, e.g., argon, xenon, a gaseous fluorinated aliphatic carbon which is heavier than air and does not interfere with the fluorinated organic compound, SF6, and any mixture thereof. Fluorinated organic carbonates are highly suitable as solvents or additives for solvent in Li ion batteries and consequently, must be kept in a very pure state even during expanded times of storage. The argon or xenon gas atmosphere prevents the intrusion of air or moisture even if the container is opened and the liquid handled in an environment of common air. A method of storing one or more fluorinated organic carbonates in a safe manner.Type: GrantFiled: December 14, 2009Date of Patent: October 21, 2014Assignee: Solvay Fluor GmbHInventor: Jens Olschimke

Publication number: 20120157695Abstract: Crude fluoroethylene carbonate obtained by the fluorination of ethylene carbonate and elemental fluorine containing not more than 5% by weight of HF is purified by at least two subsequent distillation steps. The bulk of HF can be removed, if desired, in a preliminary HF removal step, e.g., by stripping, before performing the distillation. Further, if desired, a second HF removal step can be performed by contacting the crude mixture or the distillate obtained after the first distillation step with an adsorbent for HF, e.g., silica gel. The distillation can be performed batch wise. It is preferred to perform the distillation continuously. It yields purified fluoroethylene carbonate with an HF content of equal to or less than 30 ppm. The purified fluoroethylene carbonate can be applied as solvent additive for lithium ion batteries.Type: ApplicationFiled: August 17, 2010Publication date: June 21, 2012Applicant: SOLVAY FLUOR GMBHInventors: Alain Lambert, Christoph Sommer, Harald Krueger, Jens Olschimke
