Abstract
A process for producing chlorofluorobenzenes, which comprises reacting fluorine-containing nitrobenzenes of the following formula (1) with chlorine gas to obtain chlorofluorobenzenes of the following formula (2): ##STR1## wherein n and m are integers satisfying 1.ltoreq.n.ltoreq.3, 0.ltoreq.m.ltoreq.2 and 1.ltoreq.n+m.ltoreq.3.
Claims3
A continuous process for producing chlorofluorobenzenes, which comprises reacting the nitrobenzene of formula (6) in the vapor phase with 0.1 to 20 mols per mol of the nitrobenzene of formula (6) chlorine gas at 380.degree.-450.degree. C. for 5-20 seconds to obtain a chlorofluorobenzene of formula (7):
- ##STR7## wherein Y.sup.1 is Cl and Y.sup.2 is H, or Cl.
