Claim 1: A process for producing 2,6-dichlorobenzonitrile which comprises treating 2-chloro-6-nitrobenzonitrile with chlorine gas. Claim 5: The process as claimed in claim 1 wherein said 2,6-dichlorobenzonitrile is substantially free of NOX or 2-chlorobenzonitrile or 1,2,3-trichlorobenzonitrile or tetrachlorobenzene or 2,6-dichlorobenzamide. Claim 9: A process for the preparation of 2,6-dichlorobenzonitrile comprising a) cyanurization of 1,2-dichloro-3-nitrobenzene to obtain 2-chloro-6-nitrobenzonitrile, b) denitrochlorination of 2-chloro-6-nitrobenzonitrile with chlorine gas to obtain 2,6-dichlorobenzonitrile. |
