中国科学院大连化学物理研究所奚祖威研究员及其合作者最近在反应控制相转移催化直接从丙烯环氧化制备环氧丙烷的研究中取得了突破性进展,在国际上首次发现利用自行设计的控制磷钨杂多酸季铵盐催化剂,在过氧化氢的作用下实现高选择性、高转化率的直接从丙烯制备环氧丙烷。该项成果于2001年5月11日发表在Science上,被审稿人认为是一个“梦寐以求的(化学)反应(one of the‘dream reac Researcher Xi Zuwei of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and his collaborators recently made breakthroughs in the research of reaction controlled phase-transfer catalysis directly producing propylene oxide from propylene epoxidation. It was the first time in the world that the use of self-designed control phosphorous Tungsten heteropolyacid quaternary ammonium salt catalyst, under the action of hydrogen peroxide to achieve high selectivity, high conversion of propylene oxide directly from propylene. The result, published in Science on May 11, 2001, was considered by reviewers to be a "one of the 'dream' reac
