核心提示:中科院蘭州化學(xué)物理研究所綠色化學(xué)與催化中心在多相催化非光氣合成重要異氰酸酯前體(N-取代氨基甲酸酯)方面取得新進(jìn)展。
中華化工網(wǎng)訊:中科院蘭州化學(xué)物理研究所綠色化學(xué)與催化中心在多相催化非光氣合成重要異氰酸酯前體(N-取代氨基甲酸酯)方面取得新進(jìn)展。


  該課題組成功開發(fā)了一種磁性固體催化劑,以氨基甲酸烷基酯為羰源,與胺化合物反應(yīng)高效合成了一系列重要異氰酸酯的前體,且催化劑易分離回收,循環(huán)使用多次后活性依然保持良好。該技術(shù)為非光氣合成異氰酸酯前體提供了一條安全、價廉、環(huán)境友好的合成路線,具有工業(yè)應(yīng)用價值。
