| 摘 要： | 首次把超临界相引入到合成气合成C2含氧化合物反应中。结果表明，在超临界相中进行反应可大幅度提高C2含氧化合物的选择性，尤其是提高产物乙醇的选择性，抑制了高碳数含氧化合物和烃类的生成。

| Abstract: | Catalytic synthesis of C 2 oxygenated compounds from syngas in supercritical phase was reported.The effect of the reaction conditions (including supercritical medium,the molar ratio of medium and feed and temperatures) on the conversion and selectivity was discussed.The results showed that the selectivity of C 2 oxygenated compounds in supercritical phase was greatly improved,and the by products of acetic acid,acetic ester and hydrocarbons were efficiently suppressed.Although the CO conversion was slightly declined,the space time yield of C 2 oxygenated compounds basically kept the constant. |
