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. |
