    Abstract: A continuous process for the manufacture of a polyamide, the process comprising the steps of: (i) flowing a stream A comprising a molten dicarboxylic acid, or a molten dicarboxylic acid-rich mixture comprising a dicarboxylic acid and a diamine, through a first stage and at least one more reaction stage of a vertical multistage reactor, wherein the first stage is at the top of the reactor; (ii) counter-currently flowing a stream B comprising a diamine as either a vapor or a diamine-rich liquid through at least one of the stages below the first reaction stage of said vertical multistage reactor; (iii) accumulating a liquid phase material P comprising polyamide at and/or below the final stage of said reactor; wherein said reactor is equipped with internal features suitable for effecting contact between counter-currently flowing streams A and B; and wherein said process further comprises the step of agitating said liquid phase material P by injecting a gaseous stream C comprising steam, or at least one inert gas, or a mixture of steam and at least one inert gas into the reactor at or below the final stage of the reactor. The invention further provides a vertical multistage reactor configured to implement said process.

    Abstract translation: 一种制造聚酰胺的连续方法，所述方法包括以下步骤：（i）使包含熔融二羧酸或富含熔融二羧酸的二羧酸和二胺混合物的物流A流过第一阶段 以及垂直多级反应器的至少一个以上反应阶段，其中第一阶段位于反应器的顶部; （ii）通过所述垂直多级反应器的第一反应阶段之下的至少一个阶段使包含二胺的物流B作为富含蒸汽或富含二胺的液体逆流流动; （iii）在所述反应器的最后阶段处和/或之下积聚包含聚酰胺的液相材料P; 其中所述反应器配备有适于在逆流流动物流A和B之间实现接触的内部特征; 并且其中所述方法进一步包括通过将包含蒸汽或至少一种惰性气体或蒸汽和至少一种惰性气体的混合物的气态物流C喷入反应器中或低于最终物质的方式搅拌所述液相物质P的步骤 反应堆的阶段。 本发明进一步提供配置成实施所述过程的垂直多级反应器。
