chemical properties	boiling point 173 ℃, relative density 2.140, refractive index 1.5452, flash point 77 ℃.
use	used in organic synthesis, production of propiononitrile, etc. used as an intermediate in organic synthesis
production method	obtained by the addition of acrylonitrile and bromine. Acrylonitrile was added to the glass reactor, stirred and cooled to 16°C, bromine was added dropwise under light irradiation, and the dropping acceleration was controlled so that the reaction temperature did not exceed 30°C. After dripping, continue stirring until the bromine color fades. Distillate under reduced pressure and collect the fraction at 105-112 ℃(2.66kPa) to obtain the finished product. 85% yield.
