Patent number: 9302978Abstract: The present invention relates to a continuously operated adiabatic process for the preparation of nitrobenzene by nitration of benzene with nitric acid and sulfuric acid, in which the dilute sulfuric acid obtained after the nitration has taken place and the crude nitrobenzene has been separated off from the aqueous phase is concentrated for the purpose of re-use in the nitration, and after its concentration, at least one minute before it comes into contact with fresh nitric acid again an oxidizing agent is added such that a concentration of the oxidizing agent of from 10 ppm to 5,000 ppm, based on the total weight of the concentrated sulfuric acid to be recycled into the nitration, is established.Type: GrantFiled: April 24, 2014Date of Patent: April 5, 2016Assignee: Covestro Deutschland AGInventors: Antoni Mairata, Thomas Knauf

Patent number: 9302979Abstract: A bis (2-dialkylaminoethyl) ether synthesizing method is disclosed, which includes steps of: 1) synthesizing: wherein N,N-dialkylethanolamine, N,N-dialkylamine and ethyne are mixed at a mole ratio of 4:3:1-2:1:1 as a raw material; and the raw material, catalyst and solvent are added in a high-pressure clave for reaction in a sealed condition; a weight of catalyst accounts for 2.0%-10.5% of the total weight of the raw material; a reaction temperature is 50-120° C. and the reaction time is 3-7 hours; the clave is then opened after reaction and a filtrate is collected by filtering the reaction mixture; and 2) separating: wherein the filtrate obtained in the step 1) is rectified to obtain the bis (2-dialkylaminoethyl) ether as a product. The synthetic method of the bis (2-dialkylaminoethyl) ether in the present invention has many characteristics, such as simple process, high atomic economy, etc.Type: GrantFiled: April 7, 2015Date of Patent: April 5, 2016Assignee: SICHUAN ZHIJIANG ADVANCED MATERIALS CO., LTD.Inventors: Chao Zhang, Hua Zhang, Xiaoming Ye, Qi Zhang, Chuanwei Ye

Patent number: 9302980Abstract: The problem to be solved by the present invention is to easily and efficiently produce an amino acid having 2 to 7 carbon atoms as a high-purity solid without complicated operation, which is useful as a synthetic intermediate for medicines or agrochemicals. The present invention is characterized in comprising a step of precipitating solid amino acid with high purity. In the present invention, the by-produced salt composed of the sulfonic acid and the amine was removed to the mother liquor by reacting an amine with a sulfonic acid salt of amino acid in an aprotic polar solvent, or by reacting a sulfonic acid with an amine salt of amino acid in an aprotic polar solvent. The sulfonic acid salt of amino acid, for example, may be produced by reacting a N-(tert-butoxycarbonyl) amino acid with a sulfonic acid, or by reacting an amino acid tert-butyl ester with a sulfonic acid.Type: GrantFiled: January 21, 2013Date of Patent: April 5, 2016Assignee: KANEKA CORPORATIONInventors: Masatoshi Ohnuki, Akira Nishiyama

Patent number: 9302983Abstract: The present invention relates to gas phase phosgenation of amines for preparation of isocyanates. In the present invention, phosgene is prepared by reacting chlorine with an excess of carbon monoxide in a gas phase. The obtained phosgene-containing reaction mixture is divided into two streams by a thermal and/or a membrane separating process. The first stream is a low-carbon monoxide stream of no more than 1% by weight of carbon monoxide, based on a total weight of the first stream. The second stream is a carbon monoxide-rich stream of more than 10% by weight of carbon monoxide, based on a total weight of the second stream. The first stream is used as the phosgene-containing reactant stream in the gas phase phosgenation of amines to prepare isocyanates. The second stream can be recycled into the phosgene synthesis.Type: GrantFiled: November 18, 2014Date of Patent: April 5, 2016Assignee: BASF SEInventors: Vanessa Simone Lehr, Torsten Mattke, Carsten Knoesche, Heiner Schelling, Gerhard Olbert
