3-Methylpyridine N-oxide Use and Manufacturing

Methods of Manufacturing

The preparation method is prepared by reacting 3-methylpyridine and hydrogen peroxide in the presence of a catalyst. Add a certain amount of 3-methylpyridine to the reaction kettle, add the catalyst, add hydrogen peroxide dropwise at 60～75℃, and react at this temperature for 7～8h, then dehydrate under reduced pressure to obtain 3-methylpyridine-N- Oxide.

Uses

An intermediate in the preparation of nicotine derivatives.
