Polarity of tetraalkylammonium-based ionic liquids and related low temperature molten salts

Solvatochromic measurements and 1H NMR spectroscopy have been used to investigate the overall polarity of tetraalkylammonium (R3N+-CH3 with R = n-C4H9; n-C8H17) based ionic liquids (IL) and low temperature molten salts (LTMS), respectively, as function of the counter anion. Solvent acidity (SA), solvent basicity (SB), polarizability (SP) and dipolarity (SdP) parameters have been determined according to the Catalán scale. [FeII(1,10-phenanthroline)2(CN)2] (Fe), 3-(4-amino-3-methylphenyl)-7-phenylbenzol[1,2-b:4,5-b′]difuran-2,6-dione (ABF), 3-(4-N,N-dimethylaminophenyl)-7-phenylbenzol[1,2-b:4,5-b′]-difuran-2,6-dione (DMe-ABF), 4-tert-butyl-2-(dicyanomethylene)-5-[4-(dimethylamino)benzylidene]-Δ3-thiazoline (Th), and 2-[4-(N,N-dimethylamino)benzylidene]malononitrile (BMN) have been used as solvatochromic polarity indicators. Significant correlations of the SB parameter of anion X- as a function of the chemical shift of the H-atoms of R3N+-CH3X- are presented and discussed. Thus, IL solvent basicity (SB) of the anion determines the interaction strength towards those CH-bonds in the direct vicinity of the ammonium nitrogen atom.

METHOD FOR SEPARATING A CARBOXYLIC ACID IN SALIFIED FORM BEARING AT LEAST ONE HALOGEN ATOM

The subject of the present invention is a method for separating a carboxylic acid in salified form bearing at least one halogen atom at the α position of the carbonyl group from a medium comprising it. The method according to the invention, for separating a carboxylic acid in salified form bearing at least one halogen atom at the α position of the carbonyl group from an aqueous medium comprising it, is characterized by the fact that the latter is brought into contact with an onium salt leading to the formation of two phases: an organic phase comprising the salt resulting from the reaction of the salt of the carboxylic acid bearing at least one halogen atom at the α position of the carbonyl group and of the onium salt leading to the displacement of the cation from the carboxylic acid by the onium, an aqueous phase comprising the various salts, in particular the one resulting from the reaction of the cation of the carboxylic acid with the anion of the onium, and by the fact that the organic and aqueous phases are then separated and that the onium salt of the carboxylic acid is recovered from the organic phase.

METHOD FOR PRODUCING ONIUM SALTS COMPRISING ALKYL ANIONS OR ARYL SULFONATE ANIONS OR ALKYL ANIONS OR ARYL CARBOXYLATE ANIONS HAVING A LOW HALIDE CONTENT

The invention relates to a method for producing onium salts comprising alkyl anions or aryl sulfonate anions or alkyl carboxylate anions or acryl carboxylate anions by reacting an onium halide with an alkyl silyl ester or trialkyl silyl ester of an alkyl sulfonic acid or aryl sulfonic acid or an alkyl carboxylic acid or aryl carboxylic acid or the anhydrides thereof.
