Reaktionsschritte
576 g (3 mol) of 3,4-dichloronitrobenzene, 58 g (0.1 mol) of distearyldimethylammonium chloride and 139 g (2.4 mol) of potassium fluoride were reacted analogously to Example 1. After filtering with suction, the residue was dissolved in water, the organic phase was separated off and the combined organic phases were fractionated. 289 g (69%, relative to potassium fluoride employed) of 3-chloro-4-fluoronitrobenzene were obtained.
