A method for the production of 2,4 - dichlorobenzene - 5 - fluorine benzonitrile and 2,6 - dichlorobenzene - 3 - fluorine benzonitrile

摘要

a mixture of 2,4 - the other ingredients are 5 fluortoluol and 2.6 - the other ingredients are 3 fluortoluol,in economically meaningful way which not auftrennbar and individually to the corresponding benzonitrilen can be implementedthis mixture is erfindungsgemu00e4u00df in the form of ammonoxidation and then subjected to the step of benzonitrile by professional well-known methods separately.
