    Abstract: Procedimiento para la obtención de N- fosfonometilglicina a partir de una mezcla acuosa que contiene N-fosfonometilglicina, halogenuros de amonio, así como halogenuros de metales alcalinos o alcalinotérreos y, dado el caso, impurezas orgánicas, en el que: (a) se ajusta el pH de la mezcla a un valor comprendido en el intervalo de 2 a 8, (b) se efectúa una separación de la mezcla en una membrana de nanofiltración selectiva, obteniéndose un retentato enriquecido en N-fosfonometilglicina y empobrecido en halogenuros y un permeato enriquecido en halogenuros y empobrecido en N- fosfonometilglicina y (c) se obtiene la N-fosfonometilglicina a partir del retentato.

    Abstract: The invention relates to a method for the production of aldehydes or aldehydes and alcohols by hydroformylation of olefins in the presence of a complexing catalyst homogeneously dissolved in a reaction mixture, containing a metal of Group VIIIa of the periodic table of the elements and a phosphorus-free, polydentate nitrogen compound suitable for complex formation as ligand at temperatures ranging from 50 to 100° C. and pressures from 20 to 1,000 bar and recirculating the catalyst complex in the hydroformylation reaction, wherein a) derivatized polyamines are used that are substantially non-water soluble and suitable for complex formation and have a mean molecular weight of more than 1,000 Dalton and at least 10 nitrogen atoms; b) the catalyst complex remaining in the bottom of the distillation column and the excess ligands obtained from the reaction mixture are recirculated totally or partially in the hydroformylation once the hydroformylation reaction and the separation or partial separation by distillation of the aldehydes and the alcohols has been completed; c) continues or at least batchwise evacuation of at least part of the high boiler from the bottom of the distillation of the reaction mixture is then carried out.

    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
