近日,中国科学技术大学徐铜文教授、汪耀明特任教授和李震宇教授团队联合攻关,在氘代化学品制备领域取得重要进展。科研团队创新性地利用双极膜技术,成功实现了低成本、高效率的氘代酸和氘代碱制备,直接把这类比黄金还昂贵的工业原料,生产成本降低了80%,这一成果今天(9日)在国际学术期刊《自然》在线发表。
据介绍,氘代酸和氘代碱是合成抗癌药物、提升有机发光半导体器件寿命的关键原料,但传统生产存在工艺复杂、反应条件苛刻、产物纯化困难、过程能耗高等瓶颈问题,制约了下游应用。此次研究,科研团队以廉价无机盐和重水为原料,在常温下通过双极膜“一步”生成高纯度氘代酸碱,平均生产成本仅为传统方法的五分之一,整个生产过程无需使用强腐蚀性试剂或重金属催化剂,排放趋近于零,环境友好特性突出。
基于此原理,研究团队还成功将技术拓展至多种体系,实现了氘代硫酸、氘氧化钾、氘氧化钠等十余种试剂的高效制备,将为医药、新材料等领域带来新的产业机遇。
