Publication number: 20120302706Abstract: The present invention relates to a reactor (10) and a process for continuous polymerization, where the reactor (10) has an essentially tubular reactor housing (16). The reactor housing (16) has a drive (38) which runs along the geometric central axis (12) in the flow direction (22) and is configured as a central shaft. A rotatably arranged scraper or wiper (36) is provided within the reactor housing (16); the scraper or wiper (36) has at least one scraper or wiper blade (42) to run along an interior side (44) of the reactor housing (16). The rotational movement of the scraper or wiper (36) results in radial mixing of a stream within the reactor housing (16) which dominates gravity effects and, by virtue of shaping of the scrapers or wipers, optionally makes plug flow or backflow within the reactor (10) possible.Type: ApplicationFiled: July 1, 2010Publication date: November 29, 2012Applicant: LANXESS INTERNATIONAL SAInventors: Rolf Feller, Hanns-Ingolf Paul, Paul Wagner, John Lovegrove, Jörg Kirchhoff, Joachim Ritter, Ricarda Leiberich, Udo Wiesner

Publication number: 20110257342Abstract: An integrated process for the solution polymerization and subsequent halogenation of butyl rubber in a common medium is disclosed. The process comprises providing a solution polymerization reactor containing a C6 medium mixed with a monomer mixture comprising at least an isoolefin monomer and a multiolefin monomer in a mass ratio of monomer mixture to medium of from 61:39 to 80:20. Once polymerized, residual unreacted monomer mixture is separated from the rubber solution using a distillation process. The residual monomers may then be purified and recycled back into the reactor. The separated rubber solution is then halogenated. The process obviates the need for separating the rubber from the medium following polymerization, then re-dissolving it in another solvent for halogenation, thereby saving energy cost. The process optionally employs heat exchangers for the reactor feed streams to further reduce energy consumption.Type: ApplicationFiled: July 9, 2009Publication date: October 20, 2011Applicant: LANXESS INTERNATIONAL SAInventors: Hanns-Ingolf Paul, Rolf Feller, John George Arnold Lovegrove, Adam Gronowski, Andreas Jupke, Martin Hecker, Jörg Kirchhoff, Rainer Bellinghausen

Patent number: 6955917Abstract: An improved process for the purification of antibodies from human plasma or other sources is disclosed. The process involves suspension of the antibodies at pH 3.8 to 4.5 followed by addition of caprylic acid and a pH shift to pH 5.0 to 5.2. A precipitate of contaminating proteins, lipids and caprylate forms and is removed, while the majority of the antibodies remain in solution. Sodium caprylate is again added to a final concentration of not less than about 15 mM. This solution is incubated for 1 hour at 25° C. to effect viral inactivation. A precipitate (mainly caprylate) is removed and the clear solution is diluted with purified water to reduce ionic strength. Anion exchange chromatography using two different resins is utilized to obtain an exceptionally pure IgG with subclass distribution similar to the starting distribution. The method maximizes yield and produces a gamma globulin with greater than 99% purity. The resin columns used to obtain a high yield of IgG retain IgM and IgA.Type: GrantFiled: October 15, 2002Date of Patent: October 18, 2005Assignee: Bayer Healthcare LLCInventors: Patricia Alred, Scott A.
