Claims (2)

1. Способ получения фталонитрила, включающий взаимодействие ароматических соединений с аммиаком в присутствии кислорода или его смеси с инертным газом в стационарном слое катализатора, отличающийся тем, что осуществляют процесс синтеза фталонитрила из фталевого ангидрида, полученного окислением нафталина, путем подачи в горячую фталовоздушную смесь аммиака и пропусканием смеси над стационарным слоем катализатора γ-Al2O3 при температуре 320-350oС, с концентрацией фталевого ангидрида не более 90 об. % и кислорода не более 5,5 об. %.1. A method of producing phthalonitrile, including the interaction of aromatic compounds with ammonia in the presence of oxygen or an inert gas mixture in a stationary catalyst bed, characterized in that the process of synthesis of phthalonitrile from phthalic anhydride obtained by oxidation of naphthalene by feeding ammonia into a hot phthalonitrile mixture and passing the mixture over a stationary catalyst layer of γ-Al 2 O 3 at a temperature of 320-350 o With a concentration of phthalic anhydride of not more than 90 vol. % and oxygen not more than 5.5 vol. % 2. Способ по п. 1, отличающийся тем, что отходящие газы производства фталонитрила абсорбируют промстоками производства фталевого ангидрида, содержащими фталевую, малеиновую кислоты, 1,4-нафтохинон, и утилизируют глубоким термическим окислением промстоков. 2. The method according to p. 1, characterized in that the exhaust gases of the production of phthalonitrile are absorbed by the effluents of the production of phthalic anhydride containing phthalic, maleic acid, 1,4-naphthoquinone, and utilized by deep thermal oxidation of the effluents.
