一种氢解山梨醇制备乙二醇和1,2-丙二醇的方法
摘要：
本发明提供了一种氢解山梨醇制备乙二醇和1，2-丙二醇的方法，所述方法使用的催化剂为规整结构纳米碳纤维负载钌整体型催化剂，采用连续工艺氢解山梨醇制备乙二醇和1，2-丙二醇。使用本发明的方法，可在较为温和的反应条件下氢解山梨醇连续生产乙二醇和1，2-丙二醇，并得到令人满意的山梨醇转化率和目标产物选择性。
摘要（英）：

The invention provides a method for preparing ethanediol and 1,2-propanediol by carrying out hydrogenolysis on sorbierite, a catalyst is a regularly-structured carbon nanofiber ruthenium-loading integral type catalyst and the ethanediol and the 1,2-propanediol are prepared by carrying out hydrogenolysis on the sorbierite by adopting a continuous process. The method can be used for continuously producing the ethanediol and the 1,2-propanediol by carrying out hydrogenolysis on the sorbierite under milder reaction conditions and obtaining the satisfactory percent conversion of the sorbierite andthe selectivity of target products.
