    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.

    Abstract: PCT No. PCT/EP95/04934 Sec. 371 Date Jun. 18, 1997 Sec. 102(e) Date Jun. 18, 1997 PCT Filed Dec. 13, 1995 PCT Pub. No. WO96/20155 PCT Pub. Date Jul. 4, 1996Process for preparing solid, free-flowing water-soluble salts of aryloxy-C1-C4-alkanecarboxylic acids by reacting the aryloxy-C1-C4-alkanecarboxylic acids with a salt-forming base, the salt formation taking place in the melt in the presence or absence of an entraining agent suitable for the azeotropic removal of water or in solution in the presence of an entraining agent suitable for the azeotropic removal of water and, if appropriate, removing the entraining agent from the reaction mixture during the reaction or subsequently and then isolating the solid salts in a customary manner.
