| titleOfInvention | Acetalization catalyst, preparation method thereof and method for preparing 1,1,4, 4-tetramethoxy-2-butene |
| abstract | The invention relates to an acetalization catalyst, a preparation method thereof and a method for preparing 1,1,4, 4-tetramethoxy-2-butene, wherein the catalyst is L ewis acid or Acid is used as an active component, metal nitride and/or non-metal nitride is used as a promoter, and the promoter is loaded on coconut shell activated carbon to be used as a catalyst. The catalyst is applied to acetalization reaction of 2, 5-dimethoxy-2, 5-dihydrofuran and methanol to prepare 1,1,4, 4-tetramethoxy-2-butene. The process has the advantages of high catalyst activity, long catalyst service life, small corrosion to equipment, high raw material utilization rate, high product selectivity, environmental friendliness and the like. |
