2,6-Difluorobenzonitrile Chemical Properties,Usage,Production

Chemical Properties

white to light yellow crystal powder

Uses

2,6-Difluorobenzonitrile was used in the synthesis of:

  • poly(cyanoaryl ethers) via silyl-method
  • 2-dimethylamino-6-fluorobenzamide
  • phenolphthalein-modified polyarylene ether nitrile copolymers

Uses

2,6-Difluorobenzonitrile is a halogenated benzonitrile with fungacidal activity. 2,6-Difluorobenzonitrile is the difluoro analogue of the herbicide Dichlobenil.

Flammability and Explosibility

Non flammable

Synthesis

2,6-Difluorobenzonitrile [1897-52-5], 1- cyano-2,6-difluorobenzene, Mr 172.02, mp 29 – 30℃, forms colorless crystals. The nitrile can be produced by treatment of 2,6-dichlorobenzonitrile with potassium fluoride in sulfolane and is used as an intermediate in the synthesis of insecticides (e.g., Dimilin, Shell).

Toxics Screening Level

The initial threshold screening level (ITSL) for 2,6-difluorobenzonitrile (DFBN) is 0.2 μg/m3 based on an annual averaging time.
