| titleOfInvention | Method for preparing 1, 3-propylene glycol by coupling ethylene oxide with synthesis gas |
| abstract | A method for preparing 1, 3-propylene glycol by coupling ethylene oxide with synthesis gas relates to the field of preparing 1, 3-propylene glycol, and comprises the steps of preparing 3-hydroxypropionate by performing ring-opening-carbonylation-esterification catalytic reaction on ethylene oxide, carbon monoxide and alcohol molecules, and preparing 1, 3-propylene glycol by performing hydrogenation catalytic reaction on the 3-hydroxypropionate. The catalytic reaction of ethylene oxide, carbon monoxide and alcohol is realized by using a metal complex catalyst coordinated by N, O-ligand under the action of an organic solvent and an auxiliary agent, and the yield of 3-hydroxypropionate can reach 97%. The catalytic reaction of 3-hydroxy propionate and hydrogen is carried out by using copper-containing mixed metal silicon oxygen catalyst, and the yield of 1, 3-propylene glycol can reach 73%. The alcohol generated in the second step hydrogenation catalytic reaction can be recycled for the first step ring-opening-carbonylation-esterification catalytic reaction. |
