  A process for preparing pure triethanolamine (TEOA) by continuously distillatively separating an ethanolamine mixture comprising TEOA and diethanolamine (DEOA), by distilling off DEOA in a distillation column (DEOA column) and supplying the resulting bottom stream comprising TEOA to a downstream column (TEOA column) in which the pure TEOA is withdrawn as a side draw stream, wherein the residence time of the ethanolamine mixture in the bottom of the DEOA column is <20 minutes.

  一种通过在一个蒸馏塔（DEOA塔）中蒸馏去除DEOA，并将所得的含有TEOA的底部流向供给到下游塔（TEOA塔）中，从而连续地分离包括TEOA和二乙醇胺（DEOA）的乙醇胺混合物，从而制备纯三乙醇胺（TEOA）的方法，其中乙醇胺混合物在DEOA塔底部的停留时间<20分钟，最终从TEOA塔中作为旁路流出纯TEOA。

  The present invention relates to a process for preparing an ethanolamine having an improved colour quality. The process comprises contacting ethanolamine with an activated carbon free of one or more metals chosen from Re, Ru, Rh, Pd, Os, Ir, Pt and Ag. The contacting can be carried out at a temperature of from 10 to 200°C, and during.a period sufficient to reduce the colour of the ethanolamine, in particular a period such that the colour index (as measured according to the ASTM standard D 1209) of the ethanolamine becomes equal to or less than 50 or 40 Pt/Co. The contacting can be carried out during or after the stage of preparation of the ethanolamine, preferably during or after the stage of purification of the ethanolamine. The invention also relates to a process for manufacturing a triethanolamine (TEA) having an improved colour quality, comprising a stage (i) of synthesis of the TEA by contacting ammonia with ethylene oxide in aqueous medium, a stage (ii) of separation of a crude TEA from the aqueous medium and a stage (iii) of purification of the TEA by distillation. The process in addition comprises contacting the crude or purified TEA with an activated carbon free of one or more metals chosen from Re, Ru, Rh, Pd, Os, Ir, Pt and Ag, after the separation stage (ii), or during and after the purification stage (iii). The advantage of the claimed invention is to provide an ethanolamine which has an improved colour quality far more resistant over time, and which is obtained in the absence of any additive or metal catalyst known to contaminate the ethanolamine.

  本发明涉及一种制备具有改进色彩质量的乙醇胺的方法。该方法包括将乙醇胺与不含来自Re、Ru、Rh、Pd、Os、Ir、Pt和Ag中的一种或多种金属的活性炭接触。接触可以在10至200°C的温度下进行，且在足以减少乙醇胺的色彩的时间内进行，特别是使乙醇胺的色彩指数（根据ASTM标准D 1209测量）达到等于或小于50或40 Pt/Co的时间。接触可以在制备乙醇胺阶段期间或之后进行，最好在纯化乙醇胺阶段期间或之后进行。该发明还涉及一种制备具有改进色彩质量的三乙醇胺（TEA）的方法，包括通过在水介质中将氨与环氧乙烷接触合成TEA的阶段（i），从水介质中分离粗TEA的阶段（ii），以及通过蒸馏纯化TEA的阶段（iii）。该方法还包括在从分离阶段（ii）之后或在纯化阶段（iii）期间和之后，将粗TEA或纯化TEA与不含来自Re、Ru、Rh、Pd、Os、Ir、Pt和Ag中的一种或多种金属的活性炭接触。所述发明的优点在于提供一种乙醇胺，其色彩质量在时间上更加持久，并且在没有任何已知会污染乙醇胺的添加剂或金属催化剂的情况下获得。

  The present invention provides a method of producing an ethanolamine, with a low production ratio of a dialkanolamine (for example, less than 30% by weight). A process for producing an alkanolamine of the present invention includes reacting an alkylene oxide with ammonia to obtain a reaction product containing a monoalkanolamine, a dialkanolamine, and a trialkanolamine; separating the dialkanolamine from the reaction product; and recycling at least a portion of the dialkanolamine for the reaction of an alkylene oxide with ammonia, wherein in the recycling step, the dialkanolamine is supplied in a molar ratio of the alkylene oxide (moles) to a total amount (moles) of ammonia and the dialkanolamine of 0.08 or more and less than 0.26.

  本发明提供了一种生产乙醇胺的方法，其具有低二烷醇胺（例如，重量小于30%）的生产比率。本发明的生产二烷醇胺的方法包括将烯氧化物与氨反应，以获得含有一烷醇胺、二烷醇胺和三烷醇胺的反应产物；从反应产物中分离出二烷醇胺；并至少回收部分二烷醇胺用于烯氧化物与氨的反应，其中在回收步骤中，二烷醇胺以烯氧化物（摩尔）与氨和二烷醇胺的总量（摩尔）的摩尔比为0.08或更多但小于0.26。

  An improved process for making ethoxylated amine compounds such as ethanolamines. The improvement comprises the addition of an acid to the amine compound prior to the addition of ethylene oxide to a reactor wherein the ethoxylated amine compound is prepared. The improvement reduces the concentration of undesirable glycol ether and/or vinyl ether ethoxylate byproducts which may contribute to undesirable properties, such as color and foaming, of the ethoxylated amine compounds.
