| titleOfInvention | A kind of method utilizing zeolite molecular sieve to catalyze the selective nitration of 2-naphthyl methyl ether |
| abstract | The invention discloses a method for using zeolite molecular sieve to catalyze the selective nitration of 2-naphthyl methyl ether, comprising the following steps: S1: dissolving 6 mmol of 2-naphthyl methyl ether in 10 mL of dichloromethane, adding 5 mL of acetic anhydride and 0.3-1.1 g of zeolite Molecular sieve catalyst, slowly add 2 mmol of aluminum nitrate in a stirring state, and stir in a water bath at 25 °C for 12 h; S2: After the reaction is completed, hydrolyze acetic anhydride at 40 °C for 1 h; S3: After the hydrolysis is complete, the post-reaction solution obtained from S2 is extracted, washed, Drying; S4: rotary evaporation of the dichloromethane in the solution product obtained from S3, and evaporation and crystallization to obtain a crude extract, the raw material conversion rate reaches 85.20-100%, the yield reaches 69.88-82.02%, and the isomer ratio reaches 1.56-6.09 . The present invention uses zeolite molecular sieve to catalyze the selective nitration of 2-naphthyl ether for the first time, and ZSM-5 zeolite molecular sieve has the most significant catalytic effect. When the ZSM-5 catalyst is 0.9 g, the substrate conversion rate is high, reaching 93.98% , the yield was 77.09%, and the isomerization ratio was 6.05%. |
