Definitions
- the invention relates to ionic liquids with a low melting point.
- Ionic liquids are generally understood as meaning organic salts or mixtures thereof whose melting point is below 100 ° C. (see the review article by P. Wasserscheid and W. Keim, Angew. Chem. 2001 (112), pp. 3773-3789 ).
- These salts are typically anions such as halides, halostannates, haloaluminates, hexafluorophosphates or tetrafluoroborates combined with substituted ammonium, phosphonium, pyridinium, triazolium, pyrazolium or imidazolium cations.
- Ionic liquids have recently become highly topical. An important use is the use as a solvent for organic substances. There is a constant need for substances whose melting point is as low as possible.
- the object of the present invention was initially to provide new ionic liquids having a melting point of at most room temperature (this is understood in the context of the present invention, a temperature of 30 0 C) provide.
- the object of the invention was the melting point of ionic liquids of the type of tetraalkylammonium salts, tetraalkylphosphonium salts and the like.
- the present invention accordingly relates to compounds which are liquid at room temperature and are selected from the group of tetraalkylammonium salts, benzyltrialkylammonium salts, tetraalkylphosphonium salts and benzyltrialkylphosphonium salts, with the proviso that at least two alkyl groups are aliphatic radicals having chain lengths in the range from 8 to 10 carbon atoms and the additional proviso that that not all alkyl radicals may be identical.
- halides Cl, Br, I
- halogenostannates Cl, Br, I
- haloaluminates hexafluorophosphates
- tetrafluoroborates tetrahydridoborates
- sulfates alkyl sulfates
- hydrogen sulfates carbonates
- sulfates alkyl sulfates
- carbonates Preferably, however, are used as anions halides (chloride, bromide, iodide) or alkyl sulfates, in particular chloride.
- the compounds of the invention which are ionic liquids, have melting points below 30 0 C.
- melting points below 30 0 C.
- tetraalkylammonium halides which have identical alkyl groups, informative:
- the present invention relates to compounds of the formula (I) which are liquid at room temperature.
- radical R 1 is a benzyl radical or an alkyl radical having 1 to 4 C atoms and the radicals R 2 to R 4 are independently alkyl radicals having 8 to 10 carbon atoms and X is a halide anion or an alkyl sulfate anion of the formula [R 5 SO 4 ] " , wherein R 5 is an alkyl radical having 1 to 12 C atoms, with the proviso that not all radicals R 2 to R 4 may be identical
- X is a chloride anion.
- X is an anion selected from the group 2-ethylhexyl sulfate, octyl sulfate and decyl sulfate.
- the present invention relates to compounds of the formula (Ia) which are liquid at room temperature. [NCH 3 R 2 R 3 R 4 ] + [X] - (Ia)
- radicals R 2 to R 4 are independently alkyl radicals having 8 to 10 carbon atoms and X is a halide anion or an alkyl sulfate anion of the formula [R 5 SO 4 ] " , wherein R 5 is an alkyl radical having 1 to 12 C atoms is, with the proviso that not all radicals R 2 to R 4 may be identical.
- the compounds I and in particular I-a can be used individually or in a mixture with one another.
- all methods known to those skilled in the art can be used per se. In particular, they are prepared by reacting trialkylamines of the formula (II)
- radicals R 2 to R 4 independently of one another are alkyl radicals having 8 to 10 C atoms, with compounds R 1 -X in which X is halogen, reacting with one another in the sense of a quaternization reaction.
- R 2 to R 4 independently of one another are alkyl radicals having 8 to 10 C atoms, with compounds R 1 -X in which X is halogen, reacting with one another in the sense of a quaternization reaction.
- Mn ⁇ n; Mj / ⁇ n ;

- compositions are used, containing (a) at least 85% by weight of one or more compounds of the formula I-a
- radicals R 2 to R 4 are independently alkyl radicals having 8 to 10 carbon atoms and X is a halide anion or an alkyl sulfate anion of the formula [R 5 SO 4 ] " , wherein R 5 is an alkyl radical having 1 to 12 C atoms and (b) from 0.01 to 5% by weight of water, with the further proviso that, if the radicals R 2 to R 4 are identical, at least two different compounds Ia (in particular mixtures of the two species methyltri- n-octylammonium halide and methyltri-n-decylammonium halide), the counterion of the compounds Ia being in particular chloride.
- triallamins II whose Radicals R 2 to R 4 are of native origin and are derived from fatty alcohols of the chain length range Cg-io, which means that these are from trialkylamines Wins fatty alcohols, which contain predominantly octanol and / or decanol, such as the corresponding commercially available Lorol types of the Applicant.
- the compositions mentioned are characterized by very low melting points, sometimes even below 0 0 C.
- compositions represent a uniform homogeneous phase and are hydrophobic.
- the hydrophobicity is expressed by the good solubility in organic solvents.
- the compositions mentioned are virtually completely soluble at 20 ° C. in organic solvents such as benzene, chloroform or isopropanol.
- ionic liquids can be fed to a variety of different uses. Examples include: The use as a solvent, solvent additive, phase transfer catalyst, extractants, lubricants, gas absorbents, solvents for batteries, fixer for fragrances or heat transfer.
- Further objects of the invention are: a chemical reaction in which the solvent, solvent additive or phase transfer catalyst used is an ionic liquid according to the present invention; Electrochemical processes (eg electrolysis, electrocoating, etc.) in which the solvent used is an ionic liquid according to the present invention; A substance separation process, wherein the solvent or solvent additive used is an ionic liquid according to the present invention; Heat exchange apparatus in which an ionic liquid according to the present invention is used as the heat carrier or heat carrier additive.
