The invention relates to hydroxamic acid functionalized protonized glycine betaine type ion liquid and a preparation method thereof, belonging to the field of chemical synthesis and metal flotation agent. The hydroxamic acid functionalized protonized glycine betaine type ion liquid is prepared from carboxylic ester substituted by tertiary amine and terminal halogen through steps of quaternization,ammonolysis reaction, ion exchange reaction and the like, the synthetic route is simple, the raw material cost is low, and the large-scale is easily realized. The ion liquid has the structural features similar to protonized glycine betaine, further has the advantages of uneasiness in volatilization and combustion, good thermal stability and the like of conventional ion liquid and is hopeful to bewidely applied in the fields of metal mineral flotation agents, catalyst ligands, metal extracting agents and the like. 本发明涉及类异羟肟酸功能化的质子化甜菜碱型离子液体的制备方法，属于化学合成和金属浮选剂领域。本发明以叔胺和端位卤素取代的羧酸酯为原料，通过季铵化反应，氨解反应和离子交换反应等步骤制备异羟肟酸功能化的质子化甜菜碱
