The present application relates to a process for removing an organic compound having one or more positive charges from an aqueous solution, comprising the steps a) provision of the aqueous solution comprising the organic compound and of a hydrophobic organic solution which comprises a liquid cation exchanger, where the liquid cation exchanger is hydrophobic, and where the liquid cation exchanger has one or more negative charges and an overall negative charge, b) contacting the aqueous solution and the organic solution, and c) separating off the organic solution from the aqueous solution.

Liquid cation exchanger

A polyamide composition comprising the following components: a) at least 40 parts by weight of a polyamide whose monomer units contain an arithmetic average of at least 7.5 carbon atoms, b) 0.1 to 15 parts by weight of at least one salt with a non-metallic cation, c) 0.1 to 25 parts by weight of at least one dispersant based on esters or amides and d) an electrically conductive carbon selected from the group of carbon black, graphite powder, carbon fibers, carbon nanotubes and/or graphene, in an amount which results in a specific surface resistance of the polymer composition to IEC 60167 of 10to 10&#x3a9;, e) 0 to 5 parts by weight of at least one metal salt, and optionally f) customary assistants and additives, where the polyamide of component a) is not a PA12 if carbon nanotubes are present as component d), and where the sum of the parts by weight of components a) to f) is 100, can be used for production of mouldings with improved electrical conductivity and improved surface quality.

Composition of polyamides with low concentration of carboxamide groups and electrically conductive carbon

The invention provides a biocatalytic process for oxidation of organic compounds with the aid of an alkL gene product, and microorganisms used in this process.

Biocatalytic oxidation process with AlkL gene product

The invention relates to plastics composite moldings obtainable via welding in an alternating electromagnetic field, in which the weld is obtained with the aid of a plastics material which comprises nano-scale, magnetic oxidic particles, which are composed of aggregated primary particles, and where the primary particles are composed of magnetic metal oxide domains whose diameter is from 2 to 100 nm in a non-magnetic metal oxide matrix or non-magnetic metalloid oxide matrix.

Plastic composite moulded bodies obtainable by welding in an electromagnetic alternating field

The invention relates to the use of a molding composition which comprises at least 50% by weight of a copolyamide, which is composed of the following monomer combination:

Transparent moulding compound

Compositions comprising an organic polymer as the matrix and inorganic particles as the filler and exhibiting in mixture The compositions can be prepared in a number of way, for example, by reprecipitation from the dissolved state or by mixing in an extruder and are used for preparing fibers, films and shaped articles with improved mechanical properties.
