摘　　要：综述了二甲基二环氧乙烷(DMD)的制备方法、结构特点、选择性氧化的化学特性、与木质素的相关反应机理及DMD在纸浆漂白中的作用。DMD作为一种强的亲电氧化试剂,具有良好的脱木质素能力和选择性。DMD作为漂白剂单独用于纸浆漂白,可以使纸浆达到较高的白度;DMD作为多段漂段间的活化剂,可提高后续漂白的效果。不同于传统含氯漂白的污染性,DMD的低污染和高漂白效率的特点,使其在纸浆全无氯漂白方面有着良好的应用前景。The preparation, structural features, the chemical property of selective oxidation, related reaction mechanism with lignin of dimethyl ethylene oxide （DMD） and its effect on the pulp bleaching were briefly introduced. As a strong electrophilic oxidation reagent, DMD had the good ability and selectivity of delignification. When used for pulp bleaching alone, DMD could achieve higher brightness of pulp. While as the activating agent of different bleaching stage, it could improve the effect of the following bleaching. Different from the pollution of chlorine bleaching, DMD had low pollution and higher bleaching effectiveness, which could help it had a good application prospect in the totally chlorine free bleaching of pulp.
