Abstract
The solution concerns a method of production of 4-amino-1-phenyl-5-chlor-6-oxo-1H-pyridazine by reaction of 4.5-dichlor-1-phenyl-6-oxo-1H-pyridazine with water solution of ammoniac in presence of sodium salt of phenol-4-sulphonic acid as catalyser and superficially active agent based on dialkyl sulfosuccinate in mutual molar ratio of 4.5-dichlor-1-phenyl-6-oxo-1H-pyridazine and ammoniac 1.2 to 50 at a temperature of 100 to 200 degrees C and pressure of 1.0 to 5.0 MPa, where the reaction proceeds in presence of technical catalyser of sodium salt of phenol-4-sulphonic acid containing sodium chloride and ammonium chloride. The solution can be used in chemical industry.
