| titleOfInvention | A kind of preparation method of Jiale musk |
| abstract | The invention discloses a preparation method of musk musk. Under the action of a supported Pd catalyst, hexamethylindanol and TEBBE reagent (CAS: 67719-69-1) undergo a methylene etherification reaction and then condense the ring It is converted into Jiale musk, and the product is separated by continuous rectification; the supported Pd catalyst is expressed as Pd-X/Y, wherein, X is selected from triphenylphosphine, tributylphosphine, tricyclohexylphosphine, bis-di Phenylphosphine methane, 1,2-bisdiphenylphosphineethane, 4,5-bisdiphenylphosphine-9,9-dimethylxanthene, Y selected from carbon nanotubes, ordered mesoporous carbon , Neutral alumina, silica, molecular sieve, kaolin. The process of the invention avoids the problems of complex process, serious equipment corrosion, low safety, unfriendly environment and the like in the prior art, and the conversion rate of raw materials and selectivity of products can both reach more than 93%. |
