| titleOfInvention | The method that vinyl acetate hydroformylation prepares 1,3 propane diols |
| abstract | The present invention relates to the method that vinyl acetate hydroformylation prepares 1.3 propane diols, mainly solve the problems, such as that 1.3 propane diols catalyst activity and selectivities are relatively low in the prior art, by using the preparation method of 1.3 propane diols, comprise the following steps：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 at least one, the technical scheme selected from least one of alkali earth metal and selected from least one of VB and IVA metals metallic element selected from platinum cluster metallic element, the technical problem is preferably resolved, in the industrial production available for 1.3 propane diols. |
