Patent number: 7307190Abstract: Toluenediamine is produced and separated from by-products of the reaction by: a) hydrogenating dinitrotoluene in the presence of a catalyst, b) separating the catalyst, water and optionally solvent from the hydrogenation reaction mixture to give crude toluenediamine, and c) separating by distillation the crude toluenediamine in a separating wall column into at least four product streams P1, P2, P3 and P4. The product stream P1 is a stream containing low boilers. The product stream P2 is a stream containing o-toluenediamine. The product stream P3 is a stream containing m-toluenediamine. The product stream P4 is a stream containing high boilers and m-toluenediamine.Type: GrantFiled: July 7, 2006Date of Patent: December 11, 2007Assignee: Bayer MaterialScience AGInventors: Bernd Pennemann, Bill Brady, Rainer Buse, Gerd Greger

Patent number: 7307191Abstract: This present invention provides materials for use as solid or concentrated chemical precursors for the production of organic peroxy acids (peracids). Organic peroxy acids are formed using a precursor according to the invention when they are combined with hydrogen peroxide or a hydrogen peroxide precursor such as a percarbonate or a perborate in aqueous medium. Organic peroxy acids, such as peroxyacetic acid, are used currently to disinfect medical equipment such as endoscopes and related items.Type: GrantFiled: March 16, 2004Date of Patent: December 11, 2007Assignee: OH Technologies LLPInventors: David W. Hobson, Danny O. Helton

Patent number: 7307192Abstract: The invention relates to a process for the preparation of a crystalline isomeric mixture of compounds of formulae (I) and (II) which process comprises the following steps: a) the slow addition of aluminium chloride, in portions, to a solution comprising 1,1,3-trimethyl-3-phenylindan and isobutyric acid halide in a suitable solvent at a reaction temperature of from ?20° C. to 20° C., an isomeric mixture consisting of compounds of formulae (Ia) and (IIa) being obtained; b) enol chlorination of compounds (Ia) and (IIa), an isomeric mixture consisting of compounds of formulae (Ib) and (IIb) being obtained; c) hydrolysis of the chlorinated isomeric mixture from step b). The invention relates also to the preparation of the individual compounds (I) and (II).Type: GrantFiled: April 26, 2004Date of Patent: December 11, 2007Assignee: Ciba Specialty Chemicals CorporationInventors: Rinaldo Hüsler, Thomas Horni
