    Abstract: Improved process for the preparation of granular N-alkylammoniumacetonitrile salts Iwhere R1 to R5 are hydrogen or organic radicals, and Y- is a sulfate or hydrogensulfate anion,from an aqueous solution of the compound IIwhere R6 is C1- to C4-alkyl,which comprises evaporating this aqueous solution at a temperature of from 80° C. to 250° C. and a pressure of from 10 mbar to 2 bar to give a melt, then allowing the melt to solidify, where, during or following the evaporation, customary carrier materials and/or auxiliaries can be added, and the resulting solidified compound I is converted into the desired granular form.
