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.

Patent number: 5902890Abstract: Carotene is recovered from a native fat or oil in five process steps in an economical industrial process. The native fat or oil is catalytically reacted in known manner with an alkanol containing up to 4 carbon atoms to form fatty acid alkyl ester and glycerol. The ester phase of the reaction mixture is subjected to distillation to remove the fatty acid alkyl ester. The distillation residue obtained in the second process step is saponified, carotene is extracted from the product obtained in the third process step and the extract phase is concentrated by evaporation. A yield of at least about 80% is achieved. At the same time, a fatty acid alkyl ester suitable for further processing to fatty alcohol is provided.Type: GrantFiled: October 22, 1997Date of Patent: May 11, 1999Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Michael Nitsche, Wilhelm Johannisbauer, Volkmar Jordan

Patent number: 5710261Abstract: Aliphatic alcohols with up to 30 and especially with 6 to 18 carbon atoms are separated from a mixture of alkyl glycosides and alcohols which are unreacted during the production of these glycosides, by single or multi-stage distillation. The alcohols are distilled off by a drop film evaporator to impoverish the reaction mixture to residual alcohol contents of 5 wt % and under. The strip load of the drop film evaporator is set to at least 1.0 m.sup.3 /h m, especially at least 1.8 m.sup.3 /h m and preferably at least 3.0 m.sup.3 /h m. It is possible to reduce the alcohol content of the product to any value between 0.1 and 5 wt % at acceptable overall cost.Type: GrantFiled: January 31, 1996Date of Patent: January 20, 1998Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wilhelm Johannisbauer, Michael Nitsche, Lutz Jeromin

Patent number: 5646311Abstract: Starting from a mixture containing tocopherol, fats and/or fat derivatives, more particularly fatty acids, and optionally sterol and/or sterol derivatives, the free fatty acids present in the mixture are esterified with an alcohol. The mixture is then transesterified with an alcohol in the presence of a basic catalyst. After the transesterification, the excess lower alcohol is distilled off from the reaction mixture. The transesterification catalyst and the glycerol present, if any, are removed and the fatty acid alkyl ester is distilled off from the mixture. Distillation of fatty acid alkyl esters can be accomplished with a packed column in sequence with a wiped film evaporator. The simultaneous recovery of tocopherol and sterol is possible. Tocopherols and sterols can be separated by the crystallization of sterols from a blend of organic solvents.Type: GrantFiled: May 28, 1996Date of Patent: July 8, 1997Assignee: Henkel CorporationInventors: Tracy K. Hunt, Lutz Jeromin, Wilhelm Johannisbauer, Bernhard Gutsche, Volkmar Jordon, Herbert Wogatzki

Patent number: 5527974Abstract: The glycerol water (sweet water) accumulating in the high-pressure hydrolysis of natural fats and oils with steam into fatty acid and glycerol is continuously purified. Fats larger than 100 .mu.m in diameter are separated from the aqueous phase in a plate-type phase separator and are returned to the high-pressure hydrolysis process. The aqueous phase thus prepurified is passed through a cross-flow filtration membrane, more particularly a microfiltration membrane, and the concentrate is returned to the entrance of the plate-phase separator. Large product streams of glycerol water can be purified continuously, effectively and particularly economically despite frequent changes of provenance.Type: GrantFiled: September 29, 1994Date of Patent: June 18, 1996Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Lutz Jeromin, Wilhelm Johannisbauer, Stefan Blum, Reinhold Sedelies, Heinrich Moormann, Bernd Holfoth, Juergen Plachenka

Patent number: 5225084Abstract: A process for the separation, by sedimentation, of at least one liquid organic component dispersed in a liquid containing mainly organic materials, this organic component and the remaining liquid exhibiting a difference in density. In order to reduce considerably the standing time, it is proposed that the liquid be passed before sedimentation through a fiber bed that the organic component and the remaining liquid have different surface tensions with respect to the fiber bed, that the temperature of the liquid and the concentration of the organic component to be separated are such that, in the equilibrium state, at least two liquid phases form, and that the rate of flow of the liquid through the fiber bed lies below a maximum value dependent on the surface tension of the organic component with respect of the fiber bed and on the difference in density and surface tension between the remaining liquid and the organic component.Type: GrantFiled: October 17, 1991Date of Patent: July 6, 1993Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Georg Assmann, Bernhard Gutsche, Wilhelm Johannisbauer, Richard Ridinger, Jean Rigal, Rene Armengaud, Bernard Cormary
