Abstract

一种从含有六亚甲基二胺和2-氨甲基环戊基胺的混合物分离2-氨甲基环戊基胺的方法,该方法特征在于1-300毫巴的压力下通过蒸馏进行分离。

Description

从含有六亚甲基二胺和2-氨甲基环戊基胺的一种混合物分离2-氨甲基环戊基胺的方法
本发明涉及从含有六亚甲基二胺和2-氨甲基环戊基胺(AMCPA)的一种混合物分离2-氨甲基环戊基胺的方法。
在基于金属如镍、钴、铁、铑或钌的催化剂存在下己二腈向六亚甲基二胺的完全氢化以及得到六亚甲基二胺和6-氨基己腈的部分氢化一般在例如下列文献中被公知:K.weissermel,H.-J.Arpe,Industrielle Organische Chemie,第三版,VCH VerlagsgesellschaftmbH,Weinheim,1988,第266页,US-A-4601859,US-A-2762835,US-A-2208598,DE-A-848654,DE-A-954416,DE-A-4235466,US-A-3696153,DE-A-19500222,WO92/21650和德国专利申请19548289.1。
副产物包括六亚甲基亚胺(HMI),1,2-二氨基环己烷(DACH)和氨甲基环戊基胺(AMCPA)。
US-A-3696153揭示通过这种氢化得到六亚甲基二胺,其含有非常困难从混合物中分离的AMCPA副产物。
本发明的任务是提供了一种用简单的技术和经济的方式从主要含有六亚甲基二胺和AMCPA的混合物中分离AMCPA的方法。
我们已经发现本发明的目的通过从含有六亚甲基二胺和2-氨甲基环戊基胺的混合物分离2-氨甲基环戊基胺的方法实现,该方法包括在1-300毫巴压力下通过蒸馏进行分离。
己二腈的部分或者完全氢化可以根据任何一种已知方法进行,例如根据一种前面提到的描述在US-A-4601859,US-A-2762835,US-A-2208598,DE-A-848654,DE-A-954416,DE-A-4235466,US-A-3696153,DE-A-9500222或WO92/21650中的方法,通常是,在含镍、钴、铁或钌催化剂存在下进行氢化。使用的催化剂可以是载体催化剂或者非载体催化剂。作为催化剂的载体包括有,例如,氧化铝,二氧化硅,二氧化钛,氧化镁,活性炭和尖晶石。非载体催化剂的实例是拉尼镍和拉尼钴。
氢化获得一种混合物,该混合物含有六亚甲基二胺和AMCPA以及含有或者不含6-氨基己腈和己二腈。
从含有六亚甲基二胺和AMCPA的混合物的分离可以用常规方法进行,优选进行蒸馏,例如按照DE-A-19500222或德国专利申请19548289.1,同时或者连续地进行蒸馏,例如在蒸馏塔中或者在有间壁的支流取出塔(petlyuk塔)中进行,以使除去AMCPA时的下流物流提纯塔的冷凝温度通常较高,冷凝容易进行。如果存在低沸点的DACH,其可以有利地与AMCPA同时分离除去,但是除去DACH也可以在分离塔的塔顶进行。
如果存在的话,进行六亚甲基二胺的提纯之前。将有利的根据本发明的方法完全或者部分除去低沸点次要成份,如HMI,
在含六亚甲基二胺和AMCPA的混合物中,基于六亚甲基二胺的AMCPA的分离前重量比的范围通常是1-10000ppm,尤其是100-1000ppm,并且基于六甲基二胺的分离后的AMCPA的重量比范围是0-100ppm,在此本发明的方法并不受这些限制。
根据本发明从混合物中分离AMCPA蒸馏的压力为1-300毫巴,优选1-200毫巴的压力下通过蒸馏进行,该压力范围导致底部温度范围是40-160℃。
蒸馏可以考虑在常规的装置中进行,如描述在例如:Kirk-other,《化工技术百科全书》,第三版,第7卷,Johm Wiley & Sons,New York,1979,第870-881页中的装置,如筛板塔,泡罩塔或填充塔。
优选给定的蒸馏装置从塔底至塔顶的压力降范围是0-200毫巴,优选0-50毫巴,有利的压力范围在塔底是3-300毫巴,尤其是3-200毫巴,在塔顶是1-300毫巴,尤其是1-200毫巴。
特别有利的是使用具有低的压力损失,优选每个理论塔板不超过1毫巴,尤其是0.5毫巴的蒸馏塔。
尤其适合的塔是填充塔,优选用排列填料如金属薄片填料,尤其是编织金属丝填料的填充塔。
本发明的方法得到作为塔顶产物的AMCPA,通常是,如果存在的话,则在混合物中含六亚甲基二胺和AMCPA,在混合物中含有DACH和低沸点组分。
蒸馏可以在多个塔中,如2或3个塔中进行,但是优选在一个塔中进行。
六亚甲基二胺可以用二元羧酸如己二酸处理成工业上重要的聚合物。
实施例
实施例1
