The invention relates to a low-impurity fatty acid amide propyl tertiary amine production process and a low-impurity fatty acid amide propyl tertiary amine production device, which can reduce the cost and shorten the production period. The materials of the invention are dispersed and mixed with each other in the rectifying tower by means of the special structure of the unit and the movement of the fluid, thereby achieving good mixing effect, obviously shortening the production period and being beneficial to producing PKO products with low fatty acid content; the method has the advantages of no discharge problem of dimethylamino propylamine wastewater, really realizing the clean production of the fatty acid amide propyl tertiary amine, shortening the production period, reducing the production cost and the like. |
