The present invention relates to salts having uronium cations and to a process for preparing same comprising alkylating urea C(O)(NR)using an ester AR.

Ionic liquids having uronium cations and a process for making same

The present invention relates to dyes of the general formula CATY(I), where Yis an anion selected from the group of the cyanoborates, fluoroalkylphosphates, fluoroalkylborates or imidates and CATis a cation selected from the group of the azine, xanthene, polymethine, styryl, azo, tetrazolium, pyrylium, benzopyrylium, thiopyrylium, benzothiopyrylium, thiazine, oxazine, triarylmethane, diarylmethane, methine, acridine, quinoline, isoquinoline or quaternary azafluorenone dyes, for coloring plastics and plastic fibers, for the preparation of flexographic printing inks, as ball-point pen pastes, as stamp ink, for coloring leather and paper, for use in data acquisition systems, reprography, in ink microfilters, in photogalvanics, laser technology and the photo industry.

Cyanoborate, fluoroalkylphosphate, fluoroalkylborate or imide dyes

The invention relates to boron-containing acids of the general formula (I) [B(R)(CN)F]H(I), where x=0, 1, 2, 3 or 4, y=0, 1, 2 or 3 x+y&#x2266;4, and in which the ligands Rmay be identical or different and Rstands for a perfluorinated or partially fluorinated C-alkyl group and where the CN group is bonded to the B atom via the C atom, and complexes thereof with a solvent, to salts comprising a cation and the anion of a selection of the acids according to the invention, and to processes for the preparation of the salts.

Strong boron-containing acids, the preparation and use thereof

The present invention relates to salts having thiouronium or uronium cations, to processes for the preparation thereof, and to the use thereof as ionic liquids.

Ionic liquids having uronium or thiouronium cations

The invention relates to salts having alkoxytris(fluoroalkyl)borate anions which on the one hand are used for the synthesis of ionic liquids, but on the other hand can be employed per se as ionic liquid, and to processes for the preparation thereof.

Salts having alkoxytris(fluoroalkyl)borate anions

The present invention relates to ionic liquids of low viscosity and high electrochemical stability, in particular for use in the area of electrochemistry and as solvents for carrying out chemical reactions.

Ionic liquids with bis[bis(pentafluoroalkyl)phosphinyl]imides

The invention relates to a method for producing onium salts with tetrafluoroborate anion by reacting an onium halide with an oxonium tetrafluoroborate, sulfonium tetrafluoroborate, or triphenylcarbonium tetrafluoroborate.

Process for the preparation of onium salts with a tetrafluoroborate anion having a reduced halide content

The invention relates to compounds of the formula (I), in which X, -Q-Q- and Rhave the meaning indicated in Claim, as ionic liquids, and to a process for the preparation thereof. 

Ionic liquids having fluoroalkyltrifluoroborate anions

The invention relates to a process for the preparation of onium alkylsulfonates by reaction of an onium halide or carboxylate with a symmetrically substituted dialkyl sulfite or with an asymmetrically substituted dialkyl sulfite at temperatures of 50 to 170&#xb0; C.

Process for the preparation of onium alkylsulfonates

The present invention relates to dyes of the general formula CATY(I), where Yis an anion selected from the group of the cyanoborates, fluoroalkylphosphates, fluoroalkylborates or imidates and CATis a cation selected from the group of the azine, xanthene, polymethine, styryl, azo, tetrazolium, pyrylium, benzopyrylium, thiopyrylium, benzothiopyrylium, thiazine, oxazine, triarylmethane, diarylmethane, methine, acridine, quinoline, isoquinoline or quaternary azafluorenone dyes, for colouring plastics and plastic fibres, for the preparation of flexographic printing inks, as ball-point pen pastes, as stamp ink, for colouring leather and paper, for use in data acquisition systems, reprography, in ink microfilters, in photogalvanics, laser technology and the photo industry.

The present invention relates to salts having guanidinium cations, to processes for the preparation thereof, and to the use thereof as ionic liquids.

Ionic liquids containing guanidinium cations

The invention relates to a process for the preparation of onium salts having a low chloride content by reaction of an onium chloride with an acid, where the hydrochloric acid forming is removed by azeotropic distillation by coordination to an organic solvent which forms an azeotropic mixture with water.

Process for the preparation of onium salts having a low chloride content

A process for the preparation of alkali metal cyanoborates, the further conversion thereof into salts comprising cyanoborate anions and organic cations, these salts, and the use thereof as ionic liquids are described.
