摘要

PURPOSE: A manufacturing method of phthalonitriles is provided to easily control temperature of a reactor and to have a low use amount of reaction raw material gas, and to irmpove yield of phthalonitriles.;CONSTITUTION: A manufacturing method of phthalonitriles comprises a step of conducting a first ammoxidation by introducing a first raw material into a first reaction region; a step of adding a second raw material to the product, introducing the result to the second reaction region and conducting a second ammoxidation; a step of repeating the previous steps to obtain phthalonitriles.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) First raw material; (BB) Generated reaction gas; (CC) Catalyst; (DD) First reaction region; (EE) Second reaction region; (FF) Coolant; (GG) Second raw material
