  Process for utilizing a reaction zone containing a catalyst to interchangeably conduct separate organic amine condensation reactions and a separation zone to interchangeably conduct separations of the reaction product streams of such reactions. A first organic condensation reaction using a first reactant or set of reactants is conducted in the reaction zone in the presence of a catalytically effective amount of the catalyst and at a temperature and pressure sufficient for the first organic condensation reaction to occur. Then, after termination of the first organic condensation reaction, a second organic condensation reaction using a second reactant or set of reactants is conducted in the reaction zone in the presence of a catalytically effective amount of the catalyst and at a temperature and pressure sufficient for the second organic condensation reaction to occur. The reaction product from each of the separate organic reactions is separated into at least one component, e.g., reaction product, using the same separation zone. The reaction zone contains at least two distillation columns, preferably five distillation columns.

  利用含有催化剂的反应区交替进行单独的有机胺缩合反应，以及利用分离区交替进行这些反应的反应产物流的分离的工艺。在反应区中，在催化剂有效量的存在下，在足以发生第一个有机缩合反应的温度和压力下，使用第一种反应物或一组反应物进行第一个有机缩合反应。然后，在第一有机缩合反应终止后，在催化剂的有效催化量存在下，在足以发生第二有机缩合反应的温度和压力下，在反应区中使用第二反应物或一组反应物进行第二有机缩合反应。来自每个独立有机反应的反应产物使用相同的分离区分离成至少一种组分，例如反应产物。反应区至少包含两个蒸馏塔，最好是五个蒸馏塔。
