本发明公开了一种N‑二环丙基甲基‑N'‑苯基‑1,4‑苯二胺及其制备方法和应用,以对氨基二苯胺和二环丙基甲酮为原料,在催化剂作用下进行催化加氢反应,得到N‑二环丙基甲基‑N'‑苯基‑1,4‑苯二胺。本发明N‑二环丙基甲基‑N'‑苯基‑1,4‑苯二胺合成工艺简单、反应条件较温和、成本低、反应副产物少、产品质量稳定、收率较高,N‑二环丙基甲基‑N'‑苯基‑1,4‑苯二胺分子量大,可以作为防老剂使用,与防老剂4010NA和4020相比,耐迁出、衔接性好,具有优异的耐臭氧老化性能、抗曲挠龟裂性能、耐变色性能和耐水抽出性能,且不易喷霜,提高了轮胎的外观质量。
The invention discloses N-dicyclopropyl methyl-N '-phenyl-1, 4-phenylenediamine as well as a preparation method and application thereof.The N-dicyclopropyl methyl-N'-phenyl-1, 4-phenylenediamine is obtained by taking p-aminodiphenylamine and dicyclopropyl ketone as raw materials and performing catalytic hydrogenation reaction under the action of a catalyst. The N-dicyclopropyl methyl-N '-phenyl-1, 4-phenylenediamine disclosed by the invention is simple in synthesis process, relatively mild in reaction condition, low in cost, few in reaction by-products, stable in product quality and relatively high in yield, the molecular weight of the N-dicyclopropyl methyl-N'-phenyl-1, 4-phenylenediamine is large, the N-dicyclopropyl methyl-N '-phenyl-1, 4-phenylenediamine can be used as an anti-aging agent, and compared with anti-aging agents 4010NA and 4020, the N-dicyclopropyl methyl-N'-phenyl-1, 4-phenylenediamine has the advantages of migration resistance, good cohesion and good stability. The rubber composition has excellent ozone aging resistance, flexural cracking resistance, discoloration resistance and water extraction resistance, is not easy to bloom, and improves the appearance quality of tires.
