Publication number: 20110201858Abstract: In a process for producing cumene from acetone and benzene, a feed stream comprising acetone is contacted with hydrogen in the presence of a hydrogenation catalyst in a first reaction zone under hydrogenation conditions sufficient to convert at least part of the acetone to isopropanol and produce a first liquid effluent stream rich in isopropanol and a first vapor stream rich in unreacted hydrogen. Benzene is then added to at least part of the first liquid effluent stream, without intermediate purification of the first liquid effluent stream, and optionally to at least part of the first vapor stream, to form a second feed stream.Type: ApplicationFiled: September 23, 2009Publication date: August 18, 2011Applicant: BADGER LICENSING LLCInventors: Shyh-Yuan Henry Hwang, Dana E. Johnson, Joseph C. Peters, Chung-Ming Chi, Kevin J. Fallon, Francis A. Demers

Patent number: 7868218Abstract: A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene and one or more alkanes are introduced into said first alkylation reaction zone, having operating conditions, e.g., temperature and pressure, which are controlled effective to cause the alkylatable aromatic compound to be partly in the vapor phase and partly in the liquid phase with the ratio of liquid volume to vapor volume of the feed in each zone to be from about 0.5 to about 10.Type: GrantFiled: June 9, 2010Date of Patent: January 11, 2011Assignees: ExxonMobil Chemical Patents Inc., Badger Licensing, LLCInventors: Michael C. Clark, Brian Maerz

Patent number: 7820866Abstract: An improved process for the manufacture of a polyphenol compound such as bisphenol-A by introducing into a reaction zone a phenolic compound reactant, a carbonyl compound reactant, and a catalyst promoter comprising bismethylthiopropane added to the reaction system in certain specific locations, and reacting the ingredients within the reaction zone in the presence of an acid catalyst.Type: GrantFiled: May 4, 2006Date of Patent: October 26, 2010Assignee: Badger Licensing LLCInventors: Stephen W. Fetsko, Steven D. Evitt

Patent number: 7772448Abstract: A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene and one or more alkanes are introduced into said first alkylation reaction zone. The operating conditions, e.g. temperature and pressure, of the first alkylation reaction zone are controlled effective to cause the alkylatable aromatic compound to be partly in the vapor phase and partly in the liquid phase, and the ratio of the volume of liquid to the volume of vapor of the feed in each zone to be from about 0.1 to about 10. The aromatic compound and the alkene of the feed are reacted in the presence of the alkylation catalyst to form an effluent comprising the alkylaromatic compound, unreacted alkylatable aromatic compound, any unreacted alkene and the alkane.Type: GrantFiled: January 28, 2009Date of Patent: August 10, 2010Assignees: Badger Licensing LLC, ExxonMobil Chemical Patents Inc.Inventors: Michael C.

Patent number: 7504527Abstract: An integrated process for the production of a dialkyl carbonate and a diol from an alkylene oxide, carbon dioxide and an aliphatic monohydric alcohol is described in which an alkylene oxide is first reacted with carbon dioxide in the presence of a halogen-free carbonation catalyst to provide a corresponding cyclic carbonate and the cyclic carbonate is then reacted with an aliphatic monohydric alcohol in the presence of the carbonation catalyst and/or a transesterification catalyst and recycling the carbonation catalyst to provide a corresponding dialkyl carbonate and diol, wherein the dialkyl carbonate product exhibits a halogen concentration of about 5 ppm or less.Type: GrantFiled: August 15, 2003Date of Patent: March 17, 2009Assignee: Badger Licensing, LLCInventors: Richard H.

Patent number: 7501547Abstract: A process is described for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene and one or more alkanes are introduced into said first alkylation reaction zone. The first alkylation reaction zone is operated under conditions of temperature and pressure effective to cause alkylation of the aromatic compound with the alkene in the presence of the alkylation catalyst, the temperature and pressure being such that the aromatic compound is partly in the vapor phase and partly in the liquid phase. An effluent comprising the alkylaromatic compound, unreacted alkylatable aromatic compound, any unreacted alkene and the alkane is withdrawn from the first alkylation reaction zone and then supplied to the second alkylation reaction zone without removal of the alkane.Type: GrantFiled: May 10, 2006Date of Patent: March 10, 2009Assignees: ExxonMobil Chemical Patents Inc., Badger Licensing, LLCInventors: Michael C.
