摘要（英）：

The invention relates to an efficient and clean manufacturing method of continuous-flow-state pipelined cation-oxidized starch. The invention aims to overcome the defects in the prior art, and provides a preparation method by which starch passes through a continuous pipeline reactor in a powder flow state to respectively complete cationization reaction and oxidation reaction, so that the reaction process does not generate waste water. The invention has the advantages of short time, low energy consumption, stable product quality and the like. The method comprises the following steps: 1) cationization reaction: premixing a cationization reagent and a cation activating catalyst for activation; carrying out continuous pipeline reaction with the original starch; and 2) oxidation reaction: adding an oxidant and an oxidation activating catalyst into the previous reaction system, and continuously obtaining the cation-oxidized starch crude product in the pipeline reactor. The cationization reaction can be carried out after the oxidation reaction.
