Abstract: The fluid de-ionizing medium is used for intermittent or continuous removal or ions from a cooling medium for a fuel cell using a de-ionizing device (23), inserted in the cooling medium circuit (20) for a fuel cell device (10) having at least one fuel cell (11), with mixing of the fluid-de-ionizing medium and the cooling medium directly or via a membrane. Also included are Independent claims for the following: (a) a method for de-ionizing a cooling medium for a fuel cell; (b) a fuel cell device with at least one fuel cell and at least one fuel cell cooling circuit

Abstract: Hydroformylation of 2-8C olefins comprises: (a) catalytically reacting an olefin containing saturated hydrocarbon (SHC) with CO and H2; (b) separating off a stream of unreacted olefin and SHC and contacting it with an olefin-selective membrane to give an olefin-enriched permeate and an olefin-depleted retentate; and (c) recycling at least part of the permeate back to the reaction zone.

Abstract: The stream containing hydrogen chloride (I) and the stream containing oxygen (II) are fed into an oxidation zone. The hydrogen chloride is oxidized to chlorine. A gas and a water-free gas streams are remained through the cooling and drying. The stream reversal contains chlorine-rich, chlorine, oxygen and carbon dioxide, and the liquefaction is carried out by compression and cooling (6). The gas and the water-free gas streams contain chlorine, water, oxygen, carbon dioxide and inert gases. The Gas/liquid stream is separated into a gas stream containing chlorine, oxygen, carbon dioxide and inert gases and into a fluid stream containing chlorine, oxygen and carbon dioxide. The gas stream is fed into a membrane separation unit (9) and separated into the stream reversal and chlorine-poor, chlorine, oxygen and carbon dioxide containing gas by membrane separation. The liquid stream is separated into a chlorine stream and a stream containing oxygen and carbon dioxide by distillation. The chlorine-poor and the gas stream are led into the oxidation zone, and the chlorine poor is removed.

Abstract: Procedimiento para la obtención de N-fosfonometilglicina de la fórmula (1) a partir de una mezcla acuosa que contiene disueltos en la misma N-fosfonometilglicina, halogenuros de amonio, así como también halogenuros de metales alcalinos o alcalinotérreos y eventualmente impurezas orgánicas, en donde a) se ajusta el pH de la mezcla a un valor en el rango de 2 a 8; b) se realiza una separación de la mezcla en una membrana de nanofiltración selectiva, obteniéndose un retentato más rico en N-fosfonometilglicina y más pobre en halogenuros y un permeato más rico en halogenuros y más pobre en N-fosfonometilglicina; y c) se obtiene N-fosfonometilglicina a partir de retentato. El procedimiento descripto permite la obtención de la N-fosfonometilglicina con separación simultánea de las sales de halogenuros. La N-fosfonometilglicina, también conocida como glifosato, es un herbicida total ampliamente utilizado en el agro.

Abstract: A method for working up polyether-mono-ols (I) obtained by ring-opening polymerization of epoxides with hydroxy-functional starters in presence of heterogeneous catalysts involves separating the catalyst from the product (I) by a membrane separation process. An independent claim is also included for a method for the production of (I) by ring-opening polymerization of epoxides followed by a work-up process using a separation step as above.

Abstract: The invention relates to a method for fractionation of water soluble or dispersible synthetic polymers containing amino groups with a broad molar mass distribution by means of ultrafiltration. The polymer solution or dispersion which is to be fractionated is continuously fed into an utltrafiltration circuit comprising at least one ultrafiltration unit and the retentate with a narrower molar mass distribution and the permeate are continuously discharged in such a way that the ultrafiltration circuit is placed in a substantially stationary state. The invention also relates to polymers which can be obtained according to the inventive method and to the use thereof.

Abstract: Method for aminating hydrocarbon involves physically removing hydrogen from the reaction mixture. An independent claim is included for a procedure for the production of aniline, comprising providing benzene and ammonia separately or together in a reaction mixture, which leads to cycle that exhibits a membrane reactor with catalyst and hydrogen permeable membrane, where the reaction mixture takes place at 10-150 bar, and removing the aniline from the cycle.
