摘　　要：采用磷酸与焦磷酸钠按一定配比混合作为酯化试剂,尿素为催化剂干法制备高取代度磷酸单酯淀粉,并研究不同反应条件对磷酸单酯淀粉取代度(DS)及反应效率的影响。In this article we used phosphonic acid and tetrasodium phosphate, mixed in a certain proportion as easter reagent, and carbamide as catalyst, to prepare highly substituted corn starch phosphate monoeste by drying method. The effect of different reaction conditions on the substituted degree（DS） and reaction efficiency of starch phosphate monoester were also studied in this paper.

关 键 词：高取代度 磷酸单酯淀粉 反应效率
