摘要：The storage stability of bleach-activating acetonitrile derivatives in soliddetergent compositions was to be improved. This was essentially achieved by the use ofcompounded compounds corresponding to formula RRRNCHCN X, in which R, RandRindependently of one another represent an alkyl, alkenyl or aryl group containing 1 to18 carbon atoms, in addition to which the groups Rand Rmay even be part of a
heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. “Compounds” of this type are produced by drying in vacuo, for whichpurpose a suspension of the acetonitrile derivative and a solid carrier material isintroduced into a mixer and the resulting mixture is dried with superheated vapor.Dishwashing detergents, more particularly machine dishwashing detergents, containabout 1% by weight to 10% by weight of this bleach boosting compound.
