HCID 51520946-Chloro-3-pyridinecarbonitrile

Procedure

passing a vaporized feed stream including 3-cyanopyridine, chlorine and an inert gas into a first reaction zone having a hot spot at a temperature of about 350° C. to about 420° C., and subsequently passing the stream through a second reaction zone having a temperature of about 200° C. to about 340° C., so as to produce 2-chloro-5-cyanopyridine.

Workup

  1. customat a temperature of about 350° C. to about 420° C.
  2. customa temperature of about 200° C. to about 340° C.
