Abstract: An epichlorohydrinamine polymer has a ratio of amine units to epichlorohydrin units of from 0.8:1.2 to 1.0:1.0, dimethylaminopropylamine and benzylamine preferably being used as amine and/or ammonium units. The novel epichlorohydrinamine polymer is used, for example, for the surface treatment of semifinished leather products and textile materials.

Abstract: Production of (S,S)/(R,S)-N,N'-ethylenediaminedisuccinic acid comprises reaction of ethyleneimine, maleic acid anhydride or salts and L-aspartic acid, L-glutamic acid or L-cysteine in the presence of a base. A process for the production of (S,S)/(R,S)-N,N'-ethylenediaminedisuccinic acid, analogous compounds or their salts (I) comprises reaction of maleic acid anhydride or a maleic acid salt with ethylene imine in the presence of a base, followed by reaction of the product with L-aspartic acid, L-glutamic acid or L-cysteine in the presence of a base and optionally acidification with an acid.

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: The invention relates to a method for the hydroformylation of olefins with at least 7 carbon atoms. According to said method a) the olefin is subjected to a hydroformylation reaction together with carbon monoxide and hydrogen in the presence of a complex consisting of rhodium and a polymeric complex ligand with more than 10 nitrogen atoms and having a molar mass greater than 1000 g/ mol, as well as a solubilizing agent, at a temperature of between 40 and 200 DEG C and a pressure of between 1 and 600 bar in a reaction zone, such that in these reaction conditions the solubilizing agent together with the olefin and the resulting hydroformylation product forms a largely uniform phase in which the complex is solubilized; b) in said reaction mixture a phase separation into a phase rich in solubilizing agent and a phase poor in solubilizing agent is induced, the complex preferably being present in the phase rich in solubilizing agent and the hydroformylation product preferably present in the phase poor in solubilizing agent; and c) the above phases are separated. Phase separation is preferably induced by cooling or by addition of a phase-separating agent such as water.
