Изобретение относитс к способам получени дициклогексиламина, наход щего разнообразное применение в органическом синтезе.The invention relates to methods for producing dicyclohexylamine, which has various uses in organic synthesis.
Известен способ получени дициклогексилами а путем гидрировани анилина в присутствии катализатора никел на асбесте или паллади на асбесте при повышенной температуре с последующим выделением целевого продукта известными приемами. Выход целевого продукта на .катализаторе палладий на асбесте в первом опыте -составл ет 81%, во BTOpOiM (используют этот же катализатор) 69%, а в третьем 35%. Таким образом, известный -опособ характеризуетс низкой активностью катализатора в р де последовательных опытов, проведенных с одной и тойA known method of producing dicyclohexyl a by hydrogenating aniline in the presence of a nickel catalyst on asbestos or palladium on asbestos at elevated temperatures, followed by isolation of the target product by known methods. The yield of the target product on the catalyst, palladium on asbestos in the first experiment is 81%, in BTOpOiM (the same catalyst is used) 69%, and in the third 35%. Thus, the known α-method is characterized by a low catalyst activity in a number of consecutive experiments carried out with the same
же навеской катализатора, что, в свою очередь , приводит к уменьшению выхода целевого продукта.the same amount of catalyst, which, in turn, leads to a decrease in the yield of the target product.
С целью повышени активности катализатора , предлагаетс гидрирование анилина вести в присутствии нитробензола, который желательно брать в количестве 0,01 - 1 вес. %.In order to increase the catalyst activity, hydrogenation of aniline is proposed to be carried out in the presence of nitrobenzene, which is desirable to be taken in an amount of 0.01-1 weight. %
Пример. Гидрирование аиилина осуш.ествл ют на катализаторах иикель на асбесте и палладий на асбесте, приготовленных по Зелинскому , при 180°С в лабораторной установке проточного типа с непрерывной подачей вещества в токе водорода. Изменение активности «атализаторо в и выходов продуктов в р де последовательных опытов показано в табл. 1, 2 и 3.Example. Hydrogenation of aiiline was dried on catalysts of nickel on asbestos and palladium on asbestos prepared according to Zelinsky at 180 ° C in a laboratory flow-type installation with a continuous feed of the substance in a stream of hydrogen. The change in the activity of the analyzer and the yields of products in a number of consecutive experiments is shown in Table. 1, 2 and 3.
