| titleOfInvention | The method for preparing 1,3 propane diols |
| abstract | The present invention relates to the method for preparing 1,3 propane diols, mainly solves vinyl acetate and successively prepares 1 through hydroformylation, hydrogenation and hydrolysis route, the yield of 1,3 propane diols and the problem of low selectivity during 3 propane diols.By using the method for preparing 1,3 propane diols：Vinyl acetate hydroformylation obtains 3 acetoxyl group propionic aldehyde；3 acetoxyl group hydrogenation of propionaldehyde obtain 3 acetoxyl group propyl alcohol；The hydrolysis of 3 acetoxyl group propyl alcohol obtains 1,3 propane diols；Hydroformylation catalyst uses SiO 2 、Al 2 O 3 Or its mixture is carrier, active component includes rhodium, lanthanide element and the technical scheme selected from least one of VA and VB metallic element, the technical problem is preferably resolved, in the industrial production available for 1,3 propane diols. |
