Abstract

This invention refers to new method for isolation and repeated usage of remaining agents from the sewage of agents from sewage of 5-amino-4-chlorine - 2 - phenyl - 3(2H) - pyri¬¬da¬zinon synthesis ha¬ving the for¬mula: that is achieved by the acidification of sewage, isolation of the sedimentation and subsequent chlorination to the production of 4,5-dichloro-2-phenyl-3(2H)-pyrida¬zinone.
