摘要： The present invention discloses the device and method for continuously preparing high-purity AKD without solvent. The adopted device includes a kind of reactor which could make continuous mixing reaction of raw materials. The main preparation process is: firstly, the tertiary amine is continuously fed into the reactor from starting end and the acyl chloride is continuously fed from three to ten line; secondly, under the operating state of reactor, the main motor drives the internal cylinder to rotate in relation to external cylinder, forcing the fed materials to be conveyed and stirred by blades in the conveying section of annular column passage and forcing the fed materials to be sheared and mixed by relative movement of shearing blades and kneading blades at mixing section. Due to alternate arrangement of conveying section and mixing section along the axial direction of annular column passage, it causes the sufficient reaction of fed materials and controls the material temperature through internal and external heat exchange systems until the reaction products are discharged continuously from outlet. The device and process adopted by the present invention could realize the disperse generation of reaction heat and sufficient material mixture and complete reaction to make it easy to control the reaction temperature and material viscosity and decrease the generation of side reaction to ensure the high purity of products.
