    摘要： Urethanes are made by reacting an organic nitro compound with an organic compound containing at least one hydroxyl group in the presence of carbon monoxide, hydrogen and a catalyst system. The carbon monoxide and hydrogen are used in quantities such that the molar ratio of CO to H.sub.2 is from 0.3:1 to 3:1. The catalyst system is made up of at least one noble metal or compound of a noble metal from Group VIIIB of the Periodic System of Elements, at least one organic nitrogen base and a co-catalyst combination of iron or copper oxidic or hydroxidic compound and a chloride compound. The product urethanes are useful in the production of isocyanates and pesticides.

    摘要： Urethanes are made by reacting a primary amine with carbon monoxide and a compound containing at least one hydroxyl group in the presence of an oxidizing agent and a catalyst system. The catalyst system is made up of (i) a noble metal and/or a noble metal compound of a metal of the Eighth Secondary Group of the Periodic System of Elements and (ii) an oxidizing quinoid and/or a compound capable of being converted to an oxidizing quinoid compound under the reaction conditions. The catalyst system may optionally include (iii) metal compounds of elements of the Third to Fifth Main Groups and/or First to Eighth Secondary Groups of the Periodic System of Elements and/or (iv) a tertiary amine. This reaction is generally carried out at a temperature of from 100.degree. to 300.degree. C. and at a pressure of from 5 to 500 bars. The product urethanes are useful in the production of isocyanates and pesticides.

    摘要： A urethane is produced by reacting an organic nitro compound with carbon monoxide and an organic compound containing at least one hydroxyl group in the presence of a catalyst and a co-catalyst. This reaction is conducted in the liquid phase at elevated temperature and pressure. The catalyst employed is an element and/or compound of an element from the group of noble metals of the 8th Secondary Group of the Periodic Table. The co-catalyst used is formed from (1) a component taken from the group consisting of iron oxychloride, a mixture of iron compounds containing iron oxychloride and oxide-chloride combinations and (2) metallic iron or an iron alloy in finely divided or high surface form. The oxides which may be used in the oxide-chloride combinations of co-catalyst component (1) are the oxides and/or oxide hydrates of tetravalent tin, trivalent chromium, hexavalent molybdenum, hexavalent tungsten, pentavalent vanadium, divalent iron and trivalent iron. The chlorides which may be used in this oxide-chloride combination are chlorides of the elements of Groups IIIA, IVA, VA and IB to VIIIB of the Periodic Table and/or hydrochlorides of tertiary amines.

    摘要： A hand held Radio Frequency Identification (RFID) reader is provided. The reader includes a housing having a perimeter around an inner edge. The reader also includes a full-sized dipole antenna including two antenna elements coupled by a balun transformer. The antenna has nearly a unity gain over a range of angles. The reader also includes a transceiver, coupled to the dipole antenna by a suitable cable, the transceiver adapted to send and receive signals. The reader further includes a processor for processing signals received at the antenna. The first and the second antenna segments of the dipole antenna are wrapped along the perimeter around the inner edge of the housing.
