| titleOfInvention | Process for preparing disubstituted imidazolium salt |
| abstract | R 1 and R 3 independently represent an organic radical having 1 to 20 carbon atoms, R 2, R 4 and R 5 independently represent an H atom or an organic radical comprising 1 to 20 carbon atoms, and X is at least 2 of an 1,3-disubstituted imidazolium salt of formula (I) having pK a value (measured in water or dimethyl sulfoxide at 25 ° C., 1 bar in dimethyl sulfoxide), where n represents 1, 2 or 3 The manufacturing method is disclosed. <Formula I> The process is characterized in that a) reacting the hydrogen acids of the α-dicarbonyl compounds, aldehydes, amines and anions X − with one another, b) the reaction is carried out in water or mixtures thereof with a solvent which can be mixed with water. It is done. |
