Organic Compounds -- Part Of The Class 532-570 Series > Azo Compounds Containing Formaldehyde Reaction Product As The Coupling Component > Carbohydrates Or Derivatives > Oxygen Containing Hetero Ring (e.g., Dioxirane, Etc.) > The Hetero Ring Is Five-membered The Hetero Ring Is Five-memberedThe Hetero Ring Is Five-membered 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.10/12/06 - 20060229458 - Processes for the preparation of 2-methylfuran and 2-methyltetrahydrofuran Processes are disclosed for the preparation of 2-methylfuran and 2-methyltetrahydrofuran. The continuous vapor-phase processes are commercially viable and efficient because they permit the preparation of 2-methylfuran and 2-methyltetrahydrofuran using commercially-available catalysts, namely, a reduced copper-based catalyst consisting essentially of cupric oxide, chromium (III) oxide, manganese oxide and barium chromate and ... 05/04/06 - 20060094887 - Transition metal complex having diphosphine compound as ligand A transition metal complex having 2,2′-bis[bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphino]-1,1′-binaphthyl as a ligand. The presence of the transition metal complex in the reaction system of an asymmetric reaction system allows the preparation of an objective compound having an objective absolute configuration with improved efficiency. ... 02/16/06 - 20060036103 - Process for preparing a deuterated or tritiated compound A process for labeling organic compounds with deuterium and tritium is described using specific catalysts. ... 08/11/05 - 20050176974 - Processes for the preparation of 2-methylfuran and 2-methyltetrahydrofuran Processes are disclosed for the preparation of 2-methylfuran and 2-methyltetrahydrofuran. The continuous vapor-phase processes are commercially viable and efficient because they permit the preparation of 2-methylfuran and 2-methyltetrahydrofuran using commercially-available catalysts, namely, a reduced copper-based catalyst consisting essentially of cupric oxide, chromium (III) oxide, manganese oxide and barium chromate and ... ### FreshPatents.com Support |
