A process for preparing polymeric, ionic compounds comprising imidazolium groups (polymeric, ionic imidazolium compounds for short) comprising reacting an a-dicarbonyl compound, an aldehyde, &#x2014;at least one amino compound having at least two primary amino groups (referred to as oligoamine), if appropriate an amino compound having only one primary amino group (referred to as monoamine) and a protic acid, wherein the protic acid is placed in the reactor and the oligoamine or the aldehyde and o dicarbonyl compound or the oligoamine, the aldehyde and &#x3b1;-dicarbonyl compound are fed to the protic acid.

Zeolitic materials and methods for their preparation using alkenyltrialkylammonium compounds

A process for preparing polymeric, ionic compounds comprising imidazolium groups (polymeric, ionic imidazolium compounds for short) comprising reacting&#x2014;an &#x3b1;-dicarbonyl compound,&#x2014;an aldehyde,&#x2014;at least one amino compound having at least two primary amino groups (referred to as oligoamine),&#x2014;if appropriate an amino compound having only one primary amino group (referred to as monoamine) and a&#x2014;protic acid, wherein the molar ratio of the &#x3b1;-dicarbonyl compound to the oligoamine is greater than 1.

Process for preparing polymeric, ionic imidazolium compounds of high molecular weight

The present process purifies a salt CatX, where Catis any cation and Xis an organic anion having at least 6 carbon atoms. The salt is an impurity in a composition comprising a water-soluble salt (Cat)Y, where Yis an inorganic anion or an organic anion, different from X, with at most 10 carbon atoms. The process involves converting Xinto an acid HX by adding an acid (H)Z, forming two phases: an organic phase comprising HX and an aqueous phase comprising the water-soluble salts (Cat)Zand (Cat)Yor acids (H)Y. The organic phase is separated and the aqueous phase passes over a basic anion exchanger which binds Zand Yand liberates OH, giving an aqueous mixture comprising CatOH. The organic phase and the aqueous mixture are converted into CatXand HO, optionally with addition of further HX.
