| titleOfInvention | A modified catalyst and preparation method thereof, and method for preparing N,N-dimethyl-1,3-propanediamine |
| abstract | The invention discloses a modified catalyst, a preparation method thereof, and a method for preparing N,N-dimethyl-1,3-propanediamine. The catalyst comprises an active component and a carrier modified by a bifunctional organic compound, and is generally The formula is M/O-LDH, wherein M represents an active component, and O-LDH represents a hydrotalcite carrier modified by a bifunctional organic substance; the hydrotalcite carrier is modified by a bifunctional organic substance; the modified catalyst of the present invention is used for DMAPN Hydrogenation to produce DMAPA. The DMAPA prepared by using the catalyst of the invention has few side reactions, and can prepare DMAPA with high selectivity without adding liquid ammonia or caustic alkali as an inhibitor, and the catalyst has high activity and long service life. |
