| Abstract：o Flurobenzonitrile(OFBN) was prepared from 2 chlorobenzonitrile and KF using sulfolane as a solvent. The optimum reactions were as follow :OCBW∶KF=1∶1.8(mol),OCBN∶sulfolone=1∶4( m/m ),reaction temperatare 255～260℃ and reaction time 7h. The yield of the product was 85% and the purity was more than 98%. |
| Key words：o Flurobenzonitrile; 2 chlorobenzonitrile; potassium fluoride |
