摘要： As catalysts for producing aromatic amines by hydrogenating aromatic nitrites, there are disclosed (1) the catalyst comprising a metal catalyst component comprising Ni and/or Co and a specific amount of zirconia as a carrier component, which is prepared by drying, calcining and forming a precipitate produced by adding an aqueous solution containing soluble salts of the metal catalyst component and the carrier component to an aqueous alkali solution; and (2) the catalyst comprising the metal catalyst component and the carrier component, which is prepared by filtering a precipitate produced by adding an aqueous solution containing soluble salts of the metal catalyst component and the carrier component to an aqueous alkali solution; forming the precipitate without drying to obtain a formed product; and subjecting the formed product to drying and then calcining. These catalysts are free from breaking owing to rapid generation of methane and evaporation of liquid ammonia by hydrogenolysis of high boiling by-products of the hydrogenation when reactivated after deactivation of the catalyst, which allows the long-term use of the catalysts.
摘要翻译：作为用于通过氢化芳族亚硝酸盐生产芳族胺的催化剂，公开了（1）催化剂，其包含由Ni和/或Co组成的金属催化剂组分和特定量的氧化锆作为载体组分，其通过干燥，煅烧和形成通过将含有金属催化剂组分和载体组分的可溶性盐的水溶液加入到碱性水溶液中而产生的沉淀物; 和（2）包含金属催化剂组分和载体组分的催化剂，其通过将含有金属催化剂组分和载体组分的可溶性盐的水溶液过滤到碱水溶液中制备的沉淀物; 在不干燥的状态下形成沉淀物，得到成形品; 对成形体进行干燥，然后煅烧。由于催化剂失活后再活化时氢化的高沸点副产物的氢解，液体氨的迅速产生和液氨的蒸发，这些催化剂不会破裂，这允许长期使用催化剂。

摘要： A di(aminomethyl)-substituted aromatic compound is produced by a two-stage hydrogenation. In the first stage, an aromatic dinitrile is hydrogenated into a cyano(aminomethyl)-substituted aromatic compound in the presence of a Pd-containing catalyst. The resultant cyano(aminomethyl)-substituted aromatic compound is then hydrogenated in the second stage into the target di(aminomethyl)-substituted aromatic compound in the presence of a Ni- and/or Co-containing catalyst. By the above method, the di(aminomethyl)-substituted aromatic compound is produced in a high selectivity and a sufficiently high yield without reducing the catalyst life.
