| [General Description]
3,4-Dichlorobenzonitrile (3,4-DCBN) is an aromatic nitrile that can be prepared from 3,4-dichlorobenzamide. | [Flammability and Explosibility]
Notclassified | [Synthesis]
GENERAL STEPS: 3,4-Dichlorobenzaldehyde (1.0 mmol, 1.0 eq.) was dissolved in 4 mL of aqueous solution containing acetic acid (1.0 mmol, 1.0 eq.) in a 10 mL round-bottomed flask at 0°C. The reaction was carried out at 50°C with stirring for 6 hours or monitored by thin-layer chromatography (TLC) until the reaction was complete. The reaction mixture was stirred at 50 °C for 6 h or monitored by thin layer chromatography (TLC) until the reaction was complete. Upon completion of the reaction, the reaction was quenched with 10% aqueous NaHCO3 (1 mL) and subsequently extracted with ethyl acetate (3 x 10 mL). The organic phases were combined, dried with anhydrous Na2SO4, filtered and concentrated by rotary evaporator to give the crude product 3,4-dichlorobenzonitrile. The product was characterized directly unless further purification by automated silica gel fast chromatography was required to remove trace impurities (three embodiments). | [Toxics Screening Level]
The initial threshold screening level (ITSL) for 3,4-dichlorobenzonitrile is 2 μg/m3 based on an annual averaging time. | [References]
