以木薯淀粉为原料，3-氯-2-羟丙基三甲基氯化铵为阳离子醚化剂，自制碱性复合催化剂为醚化催化剂，采用微波法制备阳离子淀粉。研究探讨不同醚化剂用量、不同微波功率、不同微波时间条件下，反应体系水分含量对阳离子醚化反应效率的影响。结果表明，不同的醚化剂用量、不同的微波功率及不同的微波时间组合，获得最佳醚化反应效率所需的反应体系水分含量各有不同。醚化剂用量较高时，选用较高的体系水分含量以及较高的微波功率和较长的微波时间，可获得较高的醚化反应效率；醚化剂用量较低时，选用中等的体系水分含量以及中等的微波功率和较长的微波时间，可获得较高的醚化反应效率。

With cassava starch as raw material, chlorine-3-2-hydroxypropyl trimethyl ammonium chloride as cationic etherifying agent, homemade alkaline composite catalyst for etherification catalysts, cationic starch was prepared by microwave method. Dif-ferent dosage of etherifying agent, different microwave power, microwave time, reaction system of moisture content on the cationic etherification reaction efficiency, was studied. The results showed that the different dosage of etherifying agent, different microwave power and microwave time, got the best etherification reaction efficiency of the reaction system in different moisture content. When the dosage of etherifying agent was higher, choosed the high moisture content, higher microwave power and longer microwave time, the high etherification reaction efficiency could be obtained. When the etherification agent was lower, choosed medium system of moisture content and the microwave power of the medium and long time of microwave, the high etherification reaction efficiency could be obtained.
