【摘要】 对由1,6-己二胺(HDA)和碳酸二甲酯(DMC)合成1,6-六亚甲基二氨基甲酸甲酯(HDC)的洁净化工艺过程进行了初步研究。考察了不同固体碱催化剂对该反应的催化活性,筛选出活性较高的MgO/ZrO2。通过考察MgO负载量的影响以及对该催化剂进行XRD表征,推断处于分散相的MgO催化活性高于晶相MgO。采用高效液相色谱(HPLC)对HDC进行定量分析,考察了不同反应条件对其催化性能的影响。更多还原

【Abstract】 The clean synthesis of 1,6-dicarbamate hexane（HDC） from dimethyl carbonate（DMC） and 1,6-diamine hexane（HDA） is studied.The preparation of HDC using different catalysts is studied,and the activity of MgO/ZrO₂ is regarded better.After characterization of the catalyst,the activity of MgO in disperse phase is inferred higher than that of MgO in crystal phase.The quantitative analysis of HDC is carried out by HPLC analysis and the influence of different reaction conditions has been investigated.更多还原
