Abstract

1304734 Process for the continuous production of tetrachlorophthalonitriles BADISCHE ANILIN- & SODA-FABRIK AG 25 June 1970 [26 June 1969] 30824/70 Addition to 1244387 Heading C2C The process of the present invention is identical to that claimed in Specification 1,244,387, with the exception that isophthalonitrile or terephthalonitrile is chlorinated instead of orthophthalonitrile at an elevated temperature in a fluidized bed containing a silica gel catalyst and/or petroleum coke catalyst to form tetrachloro-, iso- or terephthalonitrile respectively.
