| titleOfInvention | Method for preparing artificial synthetic nicotine |
| abstract | The invention discloses a preparation method of artificially synthesized nicotine, belonging to the technical field of chemical synthesis. The synthesis method of the racemate (+/-) - (R, S) -nicotine and the natural optical active body (-) - (S) -nicotine provided by the invention adopts nicotinic acid ester and succinic acid diester or N-alkyl succinimide as initial raw materials, and can overcome the defects of difficult large-scale production, high cost and the like in the existing artificial nicotine synthesis technology. Specifically, the initial raw materials adopted by the method for synthesizing the racemate (+/-) - (R, S) -nicotine and the natural optical active substance (-) - (S) -nicotine are easily obtained, the preparation process is simple, the cost is low, and the prepared nicotine does not contain any harmful other tobacco compounds and is suitable for industrial large-scale production. |
