| titleOfInvention | Continuous polyamidation method-I |
| abstract | A kind of continuation method for manufacturing polyamide, the method comprise the steps of：(i) make the first stage and at least another stage of reaction that the stream A of the mixture rich in melting dicarboxylic acids comprising melting dicarboxylic acids or comprising dicarboxylic acids and diamines flows through vertical multistage reactor, wherein the first stage is in the top of the reactor；(ii) make comprising diamines stream B is with steam or the liquid form rich in diamines inversely flows through at least one of the stage below first stage of reaction of the vertical multistage reactor；(iii) at the terminal stage of the reactor and/or the liquid phase material P comprising polyamide is built up below；The wherein described reaction utensil has the internal feature for the contact being adapted to carry out between reverse flow stream A and B；And wherein the method is further included by the terminal stage of the reactor or lower section will include steam, or at least one inert gas or the air-flow C of steam and the mixture of at least one inert gas the step of injecting the reactor and stirring the liquid phase material P.The present invention further provides be configured to implement the vertical multistage reactor of the method. |
