摘　　要：简单介绍了半纤维素的化学组成及结构特点,对近十年来半纤维素的醚化改性的研究进展进行了综述,主要介绍了半纤维素的羧甲基化、甲基化、季铵化等的醚化反应。展望了半纤维素醚化改性的发展前景。in this paper the chemical constituents and the structural characterization of hemicelluloses were introduced simply. Simultaneously, the etherifying modification of hemicelluloses was summarized in latest decade years, such as carboxymethylation, methylation, and quaternization and so like. In the end, the new progress of etherifying modification of hemicelluloses was mentioned.
