"BLANKING PERFORMANCE / BLANKING PERFORMANCE COMBINATION, AND, PRODUCTS". The invention relates to granular N-alkylammoniumacetonitrile salts of the general formula (I): R ^ 2 ^ R ^ 3 ^ NR ^ 1 ^ -CR ^ 4 ^ R ^ 5 ^ -CN ^ + ^ Y ^ - ^ (I) wherein R4 is a C1 -C4 alkyl group which may be interrupted by non-adjacent oxygen atoms or may additionally carry hydroxyl groups, a C4 -C6 cycloalkyl group ~ 24 ~, a C 7 to C 24 alkaryl group or a group of the formula -CR 4 4 R 4 R 5 -CN, R 2 and R 3 each independently have one of the same. another, the meaning of R 1 or together represent, on the nitrogen atom to which they are attached, a saturated four to nine membered ring having at least one carbon atom and at least one other heteroatom from the following group: oxygen, sulfur and nitrogen, R ^ 4 ^ and R ^ 5 ^, each independently means hydrogen, a C 1 to C 24 alkyl group which may be interrupted by non-adjacent oxygen atoms or may additionally carry hydroxyl groups one C4 to C24 cycloalkyl group or C7 to C24 alkaryl group; and Y represents an anion sulfate or hydrogen sulfate in the appropriate stoichiometric amount, which are coated with a material selected from the following group: organic, inorganic, hydrophilic and hydrophobic substances. |
