  An integrated process of CO₂capture and in situ hydrogenation to formate using a tunable ethoxyl-functionalized amidine and Rh/bisphosphine system

  摘要：

  实现了CO2捕集与原位氢化为甲酸的综合过程，产率达到95%-99%，使用了可调的乙氧基功能化胺基及Rh/双磷酸酯体系，这被视为供应燃料相关产品的替代碳捕集与利用方法，以避免碳捕集与储存中的能量损失。CO2通过非挥发性胺基衍生物被捕集，同时活化形成带有双重电荷的胺基碳酸盐，随后氢化过程由Rh/双磷酸酯促进。通过调节乙氧基侧链，可以优化吸附能力和氢化效率。特别是，具有来源于1,8-二氮双环[5.4.0]-十一烯（DBU）内源氢供体的烷醇胺基显示出高CO2吸附量（摩尔比为0.95:1）和优异的氢化产率（99%）。此外，硅胶支持的烷醇胺基可以方便地回收再利用，并保持良好性能。这种碳捕集与利用路径可能成为将废弃CO2工业转化为燃料相关产品的潜在节能选择，以实现碳中和。

  A method of making an isocyanato terminated precursor for polyurethane is disclosed. The method comprises heating an isocyanate containing about two or more isocyanato groups per molecule at a temperature of up to 80 degrees Celsius and at a pressure of about 1 atmosphere. The method further comprises mixing a modified vegetable oil comprising about two or more hydroxyl groups per molecule with the isocyanate at a molar equivalent ratio of at least 2:1 isocyanate to vegetable oil for a predetermined time period to form the isocyanato terminated precursor.

  A method of making a hydroxyl terminated precursor for polyurethane is disclosed. The method comprises heating a vegetable oil-polyol mixture of modified vegetable oil containing about two or more hydroxyl groups per molecule and a polyether polyol having about two or more hydroxyl groups per molecule at a temperature of at least about 25 degrees Celsius and at a pressure of about 1 atmosphere. The mixture has a hydroxyl equivalent ratio of about 1:1 vegetable oil to polyol. The method further comprises mixing for at least about 10 minutes an isocyanate containing about two or more isocyanato groups per molecule at least about 25 degrees Celsius to the vegetable oil-polyol mixture at a molar equivalent ratio of at least 2:1 vegetable oil-polyol mixture to isocyanate to react the isocyanate with the mixture to form the hydroxyl terminated precursor.
