    • A process for producing an N,N-diethylaminophenol is disclosed, comprising subjecting an aminophenol to reductive alkylation with acetaldehyde in the presence of a solvent, a catalyst, and hydrogen is disclosed, in which the reaction mixture from which the catalyst has been removed is subjected to distillation while maintaining the temperature of the bottom at 160.degree. C. or lower to substantially remove the unreacted acetaldehyde and the solvent, the residual bottom is distilled while maintaining the temperature of the bottom at 200.degree. C. or lower to recover a crude N,N-diethylaminophenol as a distillate, and the recovered crude N,N-diethylaminophenol is contacted with a solvent to which at least one of acid sulfites and dithionites has been added, said solvent being substantially incompatible with the N,N-diethylaminophenol, in an inert gas atmosphere, followed by precipitating and recovering the N,N-diethylaminophenol by cooling. N,N-Diethylaminophenols of high purity can be obtained in high yield without involving problems, such as production of large quantities of waste water and sludge, corrosion of materials, and coloring with time.
    • 公开了一种制备N,N-二乙基氨基苯酚的方法,包括在溶剂,催化剂和氢的存在下,用乙醛对氨基苯酚进行还原烷基化,其中已除去催化剂的反应混合物为 将塔底温度维持在160℃以下,进行蒸馏,基本上除去未反应的乙醛和溶剂,蒸馏残留的底部,同时保持底部温度在200℃以下,回收粗品 N,N-二乙基氨基苯酚作为馏出物,将回收的粗N,N-二乙基氨基苯酚与添加有至少一种酸亚硫酸盐和连二亚硫酸盐的溶剂接触,所述溶剂与N,N-二乙基氨基苯酚基本上不相容, 在惰性气体气氛中,然后通过冷却沉淀并回收N,N-二乙基氨基苯酚。 可以高产率地获得高纯度的N,N-二乙基氨基苯酚,而不会引起大量废水和污泥的产生,材料腐蚀和着色随时间的问题。

    • In a process for the production of an aminophenol which comprises reacting a divalent phenol and ammonia in the absence of a catalyst or in the presence of a water-soluble catalyst, then separating the reaction mixture after the reaction to recover a separated and recovered product containing an aminophenol and the unreacted divalent phenol, and separating and purifying the aminophenol from said separated and recovered product, the process for the production of an aminophenol which is characterized by, on separating and purifying said aminophenol, contacting said separated and recovered product with an aliphatic ether substantially incompatible with said aminophenol in an inert gas atmosphere at a temperature at which said separated and recovered product melts or higher, then cooling to induce the crystallization of the aminophenol, thereafter filtering and recovering to obtain a cake mainly composed of said aminophenol, further melting and contacting this cake with an aliphatic ether in an inert gas atmosphere in the co-presence of water and a surfactant, and then cooling to induce the crystallization of said aminophenol and recovering it. According to the invention, a high-quality aminophenol can be produced.
