Yield	Reaction Conditions	Operation in experiment
87.6%	With potassium fluoride; at 140 - 150℃; for 3h;	40 into the four-necked flask 5,001,111 (^ (2.081111) 2,3-dichloro-nitrobenzene, heated to 140 (: inputs 112g (1.93mol) KF, dehydration under reduced pressure at 140 ~ 150 C insulation 3h, after completion of the dehydration was heated to 140 C, between 150 ~ 160 C to 6. 6g (0. 06mol) of tetramethylammonium chloride was added to the reactor, after the addition was completed in 165 ± 5 C incubation 8h, the reaction was stopped, after cooling, washed with water, the organic phase to distillation layered distillation, recovering 2,3-dichloro-nitrobenzene 100g, generating 2_-fluoro-3-chloronitrobenzene 240g, content 99.6%, a yield of 87.6%.
	With potassium fluoride; In 5,5-dimethyl-1,3-cyclohexadiene;	a) In a 1-liter flange flask fitted with a distillation bridge and stirrer, 139 g (2.4 mol) of potassium fluoride were introduced at 120 C. into the melt of 576 g (3.0 mol) of 2,3-dichloronitrobenzene. Subsequently, 20 g (0.19 mol) of xylene were added and the reaction suspension was azeotropically dried by application of a vacuum of 60 mbar and heating to 150 C. After the xylene had been distilled off, the distillation bridge was replaced by a reflux condenser, the reaction suspension was heated to 190 C. and stirred for 6 hours at this temperature. Amount of 3-chloro-2-fluoronitrobenzene formed: 0.5 GC area-% after 6 hours.
	With potassium fluoride; tetramethlyammonium chloride;	11. 202 g (1.1 mol) of 2,3-dichloronitrobenzene were reacted with 56 g (1.0 mol) of potassium fluoride and 10 g of tetramethylammonium chloride at 180 C. After 19 h, the conversion was over 70% (GC) with the formation of 3-chloro-2-fluoronitrobenzene.
