| titleOfInvention | Copper-rhodium-magnesium-aluminum four-component catalyst for preparing 1,2-propylene glycol by adding hydrogen directly to biodiesel-based crude glycerine and preparation method of 1,2-propylene glycol |
| abstract | The invention discloses a Cu-Rh-Mg-Al four-component catalyst for preparing 1,2-propylene glycol by directly adding hydrogen with biodiesel-based crude glycerine as a raw material and a preparation method of the 1,2-propylene glycol. The Cu-Rh-Mg-Al four-component catalyst can be synthesized by one step by a coprecipitation method and can be directly used in the preparation of the 1,2-propylene glycol by adding hydrogen with the biodiesel-based crude glycerine as the raw material after being roasted and reduced; and the efficient synthesis of the 1,2-propylene glycol is realized under the mild and green conditions by using the catalyst and the biodiesel-based crude glycerine as the raw materials. In the process of directly adding hydrogen in a 75 percent glycerine water solution at 180 DEG C and 2.0 MPa hydrogen pressure, the highest yield of the 1,2-propylene glycol after reacted for 10 hours can reach 71.2 percent; and under the same reaction conditions, the yield of the 1,2-propylene glycol by using a 75 percent glycerine-ethanol solution can reach 89.2 percent. |
