Abstract: A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.

Abstract: Method for improving selectivity and productivity during purification of charged macromolecules and particles by electrofiltration by means of membranes in the electric filed. The ratio between the electric field and the permeate flow through the membrane is kept constant.

Abstract: The present invention relates to calix[4]arenes which effectively bind alkali metal ions (Na+, K+) and transport them over phase boundaries, their preparation and use.

Abstract: A device and a process are described for membrane electrophoresis or electrofiltration. The device contains at least one input chamber, one output chamber, and one cathode chamber and anode chamber each, whereby the individual chambers are separated from one another by membranes, and are integrated into a permanently attached module with membranes, and whereby the electrodes are integrated into the module, and the module is connected to constructions enabling continuous flow through the input and output chambers, as well as through the electrode chambers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims. 37 CFR §1.72(b).

Abstract: The invention concerns a process for concentrating polymer latexes, which can be separated into a latex phase and a serum phase in a separator with the aid of an auxiliary coalescing device.

Abstract: A process for the separation and recycling of catalyst components from a chemical reaction mixture is disclosed. The process entails at least one extraction step.

Abstract: A process for the preparation of a solution of a quaternary cation and an anion from a deprotonated hydroxy aromatic in an organic solvent by means of a reactive extraction of a quaternary salt in the presence of an aqueous hydroxide solution, a hydroxy aromatic and an organic solvent is disclosed. Also disclosed is a process for the recycling of a quaternary salt phenolate solution from a reaction mixture.
