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 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 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 invention relates to a method for the production of organic salts containing bis(perfluoroalkyl)phosphinate anions. According to said method, a tris(perfluoroalkyl)phosphine oxide is reacted with an alcohol and an organic base, which is stronger than the alcohol. The invention also relates to the salts which are produced according to said method and to the use thereof as ionic liquids.

Process for the preparation of organic salts containing bis(perfluoroalkyl) phosphinate anions

The present invention relates to salts comprising bis(trifluoromethyl)imide anions and saturated, partially or fully unsaturated, heterocyclic cations, to a process for the preparation thereof, and to the use thereof as ionic liquids.
