DBPN - Reference Information
| 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. |
