FIELD: chemistry.
SUBSTANCE: proposed method for producing a mixture of phosphonitrilanilides consists in condensing a mixture of phosphonitrile chlorides with aniline in the presence of an aromatic hydrocarbon as solvent, followed by heat treatment at the temperature of 200°C, the reaction being carried out at the molar ratio of phosphonitrile chloride: aniline of 1:2, tertiary aliphatic amines are used as a catalyst and a hydrogen chloride acceptor, the condensation reaction is conducted at the temperature of 105-110°C. Triethylamine or tetramethylethylenediamine is used as a catalyst and an acceptor of hydrogen chloride. Toluene is used as an organic solvent.
EFFECT: new efficient and economical method of producing a valuable substance.
