By Condensation Of Entire Molecules Or Entire Hydrocarbyl Moieties Thereof, E.g., Alkylation, Etc.By Condensation Of Entire Molecules Or Entire Hydrocarbyl Moieties Thereof, E.g., Alkylation, Etc. patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.12/14/06 - 20060281958 - Catalytic reactive separation system for energy-efficient production of cumene The present invention relates to an atmospheric pressure, reactive separation column packed with a solid acid zeolite catalyst for producing cumene from the reaction of benzene with propylene. Use of this un-pressurized column, where simultaneous reaction and partial separation occur during cumene production, allow separation of un-reacted, excess benzene from ... 07/13/06 - 20060155155 - Method of aromatic alkylation A catalyst for use in aromatic alkylation, such as toluene alkylation with methanol, is comprised of a zeolite with pore size from about 5.0 to about 7.0 Å containing a hydrogenating metal. The catalyst may be used in preparing an alkyl aromatic product by providing the catalyst within a reactor. ... 01/26/06 - 20060020153 - Novel process for preparation of 2,6-dialkyltetralin The present invention provides a novel process for highly selective preparation of 2,6-dialkyltetralin, a key precursor for 2,6-dimethylnaphthalene (2,6-DMN), which does not require an extra step for purifying various isomers obtained from the conventional processes for 2,6-DMN. The present invention is advantageous to improve the synthetic yield, to simplify the ... 10/13/05 - 20050228204 - Process for the preparation of xylene The present invention relates to a process for the preparation of xylene from diisobutylenes. ... 09/08/05 - 20050197516 - Alkylation process with efficient effluent refrigeration An alkylation process in which a recycle stream is cooled by heat exchange with the alkylation reactor effluent is disclosed. ... ### FreshPatents.com Support |
