The present invention is related to a polymer membrane for the selective extraction of cobalt (II) ions as well as a method for extracting cobalt (II) ions using said polymer membrane.

Selective extraction film for mining application

A multilayered composite or coated substrate, comprising compounds of which at least 40% by weight are composed of alpha-amino acids linked via peptide bonds as adhesion promoters between at least two adjacent layers of the composite or between the coating and the substrate.

Use of polypeptides in the form of adhesive agents

Hydrophobins for stabilizing phases in biphasic liquid systems.

Use of hydrophobin as a phase stabilizer

Open-cell foam based on a melamine-formaldehyde condensation product, a polyurethane or a polyimide, which has been modified with hydrophobins, a method of producing such foams, and the use thereof for absorbing organic liquids, as leakage and bleeding protection for liquid stores, for liquid-liquid separation and as matrix for carrying out chemical and/or biological processes.

Open-cell foam modified with hydrophobines

The use of hydrophobins for preventing the formation of ice on surfaces, especially for the prevention of ice formation on aircraft surfaces.

Use of hydrophobins to prevent ice from forming on surfaces

The present invention relates to the use of at least one hydrophobin or at least one hydrophobin derivative in a drilling mud.

Sulfonated and oxidized indene polymers

Oligomeric triarylmethane dyes

Dyeing and printing textile materials made of cellulose fibers

An electrostatic toner contains a polymeric binder and as a charge stabilizer a polyamine whose average molecular weight is from 150 to 15,000 and wherein the nitrogen atoms are separated from each other by C.sub.1 -C.sub.13 - alkylene, which may be phenyl-substituted, or by phenylene, which may be C.sub.1 -C.sub.4 -alkyl-substituted, and are substituted by C.sub.1 -C.sub.13 -alkyl, which may be phenyl-, hydroxyl- or carboxyl-substituted, phenyl, C.sub.1 -C.sub.10 -alkanoyl, benzoyl, C.sub.1 - C.sub.6 - alkylcarbamoyl, phenylcarbamoyl or a radical of the formula CO-L-CO, where L is C.sub.2 -C.sub.8 -alkylene, the last case resulting in the crosslinking of two polyamine units.

The preparation of 1-hydroxyimidazoles of the formula I ##STR1## where the R radicals can be identical or different and are each halogen or an organic radical, it also being possible for vicinal radicals to be connected to form an aromatic or nonaromatic ring of from 3 to 12 carbon atoms, and n is from 0 to 3, entails reacting an imidazole of the formula II ##STR2## where Q is preferably hydrogen or, especially where R is not halogen, an alkali metal or alkaline earth metal cation, with an organic peroxide. The 1-hydroxyimidazole and its halogen substituted derivatives of the formula I and the acid addition salts thereof are valuable intermediates for organic syntheses.

1-hydroxyimidazole compounds

A process for preparing .beta.-naphthyl benzyl ether comprises reacting .beta.-naphthol essentially in the absence of water with an alkali metal carbonate or an alkaline earth metal carbonate and benzyl chloride in an inert water-miscible solvent at from 0.degree. to 200.degree. C.
