The present invention relates to compositions containing polymeric, ionic compounds comprising imidazolium groups. In particular, it relates to the use of polymeric, ionic compounds comprising imidazolium groups in personal care compositions and/or in biocide compositions.

Compositions containing polymeric, ionic compounds comprising imidazolium groups

A composition comprising a source of metal ions and at least one leveling agent comprising a linear or branched, polymeric imidazolium compound comprising the structural unit of formula L1 (L1) wherein R, R, Rare each independently selected from an H atom and an organic radical having from 1 to 20 carbon atoms, R4 is a divalent, trivalent or mutlivalent organic radical which does not comprise a hydroxyl group in the a or &#x3b2; position relative to the nitrogen atom of the imidazole rings is an integer. 

Composition for metal electroplating comprising leveling agent

Method of lightening the color of mixtures comprising imidazolium salts or imidazoles, wherein the mixtures are treated with an oxidant.

Method of working up mixtures comprising imidazolium salts

Process for preparing 1,3-disubstituted imidazolium salts of the formula I 

Method for the production of disubstituted imidazolium salts

Process for preparing salts KX, where Kis an organic cation and Xis an anion, by anion exchange, wherein

Process for preparing ionic liquids by anion exchange

A process for producing porous structures from polyamide by dissolving the polyamide in an ionic liquid and precipitating or coagulating the dissolved polyamide by contacting the solution with a liquid precipitant medium. Fibers are produced from the dissolved polyamide in a wet-spinning process by precipitation in protic solvents, in particular water, a C1-4-alkanol or mixtures thereof, and subsequent freeze-drying. Foils, films or coatings are produced by blade coating the dissolved polyamide onto a substrate surface, optionally spraying with protic solvent, in particular water, a C1-4-alcohol or mixtures thereof, dipping into a precipitation or coagulation bath, freeze-drying of the resulting foil, of the film or of the coated substrate. Molded parts are prepared by extracting the dissolved polyamide with protic solvents, preferably water, a C1-4-alcohol or mixtures thereof, wherein the dissolved polymer is transformed to a solid or wax-like state by cooling and extracted after subsequent molding.

Method for producing porous structures from synthetic polymers

The present invention provides a process for producing low fibrillating cellulose fibers by a dry-jet-wet spinning process wherein cellulose is treated with a solvent containing imidazolium ionic salt in a spinneret maintained at a temperature of 100-120&#xb0; C. and the spun fibers drawn to the coagulation bath containing ionic salt with the draw ratio less than 5, to produce fibers with fibrillating index less than or equal to 3.

Process for manufacturing low-fibrillating cellulosic fiber

The present process purifies a salt CatX, where Catis any cation and Xis an organic anion having at least 6 carbon atoms. The salt is an impurity in a composition comprising a water-soluble salt (Cat)Y, where Yis an inorganic anion or an organic anion, different from X, with at most 10 carbon atoms. The process involves converting Xinto an acid HX by adding an acid (H)Z, forming two phases: an organic phase comprising HX and an aqueous phase comprising the water-soluble salts (Cat)Zand (Cat)Yor acids (H)Y. The organic phase is separated and the aqueous phase passes over a basic anion exchanger which binds Zand Yand liberates OH, giving an aqueous mixture comprising CatOH. The organic phase and the aqueous mixture are converted into CatXand HO, optionally with addition of further HX.

Process for purifying ionic liquids

The invention relates to a method for producing regenerated biopolymers in the form of carbohydrates, using a solvent system that contains the biopolymers dissolved therein. The solvent system is based on a melted ionic liquid and optionally a protic solvent or a mixture thereof. The biopolymers dissolved in the solvent system are precipitated in a coagulation medium, said medium comprising a protic coagulant or a mixture of protic coagulants. The method according to the invention is characterized in that the surface tension &#x3c3; of the coagulant or the mixture of coagulants is 99% to 30% of the surface tension &#x3c3; of water, the surface tension being measured according to ASTM D 1590-60 at a temperature of 50&#xb0; C. The method according to the invention is economical and flexible and leads to advantageous products, especially in the form of staple fibers which are especially not fibrillated and have an advantageous wet to dry strength ratio.

Process for preparing salts of the formula I(B)xAwhere

A method of distilling mixtures of salts having a melting point of less than 200&#xb0; C. at 1 bar (ionic liquids). The cation of the ionic liquid has a heterocyclic ring system having at least one nitrogen atom, and all nitrogen atoms of the heterocyclic ring system have an organic group as substituent. The anion of the ionic liquid is a compound having at least one carboxylate group or at least one phosphate group. The distance from the surface via which the heat of distillation is introduced in the distillation (vaporizer surface) to the surface at which condensation takes place (condenser surface) is less than 50 cm at at least one point, with the vaporizer surface and condenser surface themselves having at least one length dimension of greater than 50 cm.
