N-(1-phenylethyl)-N'-phenyl-1,4-phenylenediamine of high purity is produced by a two-step synthesis, where in the first step 4-aminodiphenylamine reacts with acetophenone in the presence of an acidic catalyst. The reaction is performed to an incomplete conversion of 4-aminodiphenylamine, whereby an intermediate product of high purity is obtained, which is hydrogenated on a heterogeneous catalyst in the second step. N-(1-phenylethyl)-N'-phenyl-1,4-phenylenediamine can be used as a component of anti-degradation systems.
高纯度的N-(1-苯乙基)-N'-苯基-1,4-苯二胺是通过两步合成得到的,第一步中4-氨基二苯胺在酸性催化剂的存在下与苯乙酮反应。反应进行到4-氨基二苯胺未完全转化为止,得到高纯度的中间产物,第二步在非均相催化剂上进行氢化。N-(1-苯乙基)-N'-苯基-1,4-苯二胺可用作抗降解系统的组分。
