The selectivity of phthalonitrile is a key problem for the ammoxidation of o-xylene. Based on appraising tests, a catalyst ODT-88 of higher selectivity has been found. The influences of the molar ratio of air, ammonia, reaction temperature were studied. Under suitable conditions, the molar yield of phthalonitrile is 94.4%, The scale test has been finished. The industrial installation is being constructed. 氨氧化 邻苯二甲腈 邻二甲苯 ammoxidation phthalonitrile o-xylene O625.67 2001-06-01 2021-04-01 6
