Patent number: 7449088Abstract: The present invention relates to a new process for obtaining fatty acids with improved color, odor and heat stability which is characterized in that: (a) in a first step the crude acids are fed to a rectification (“precut”) column in order to remove low boiling by-products being present in the starting material as a top fraction, and (b) in a second step the bottom fraction of the precut column is fed to a sidestream column in order to obtain the pure fatty acids as the side fraction, to remove low boiling by-products which have been formed in the course of the first distillation as a top fraction and to remove high boiling by-products, either being present from the starting material or formed during the first distillation, with the residue.Type: GrantFiled: March 31, 2005Date of Patent: November 11, 2008Assignee: Cognis Oleochemicals GmbHInventors: Nataly Lausberg, Horst Josten, Georg Fieg, Thomas Kapala, Ralf Christoph, Andreas Suessenbach, Andreas Heidbreder, Ingomar Mrozek, Albrecht Schwerin

Process for producing glycerol having low aldehyde and ketone content and improved storage stability
Publication number: 20080033191Abstract: The invention describes a process for the production of glycerol of providing a vegetable oil or fat as starting material, obtaining crude glycerol from the vegetable oil or fat, and treating the crude glycerol with a reducing agent. The present invention also describes a process for the production of a medicament or pharmaceutical composition, the medicament or composition formed by combining glycerol and at least one pharmaceutically active ingredient. The present invention also describes a pharmaceutical composition or medicament composed of glycerol obtained by way of the invention and a pharmaceutically active ingredient, which compositions forms very little glyceraldehyde and dihydroxyacetone during storage.Type: ApplicationFiled: July 25, 2007Publication date: February 7, 2008Inventors: Ulrich Schoerken, David Melchior, Jochen Seifert, Carolin Meyer, Valerie Eychenne, Christiane Richard-Elsner, Horst Josten, Jean Rigal, Bernhard Gutsche, Albert Strube -

Patent number: 5973173Abstract: Pure azelaic acid is obtained by working up a reaction mixture containing C.sub.1-18 monocarboxylic acids, mainly pelargonic acid, and C.sub.4-16 dicarboxylic acids, mainly azelaic acid, obtained from the ozonolysis of oleic acid or a starting mixture containing oleic acid. All but <2% by weight of the monocarboxylic acids and part of the dicarboxylic acids with a chain length of <C.sub.9 and >C.sub.9 are separated off to obtain a prepurified product containing more than 75% by weight of oleic acid and the prepurified product is concentrated to more than 90% by weight of oleic acid in several process steps. In a first process step (1), the dicarboxylic acids with chain lengths of <C.sub.9 present in the prepurified product are removed as first runnings by fractional distillation. In a second process step (2), the bottom product obtained is reacted with water to split carboxylic anhydrides present in the bottom product.Type: GrantFiled: April 22, 1997Date of Patent: October 26, 1999Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Horst Josten, Wilhelm Johannisbauer, Manfred Lindemann, Dennis G.
