PRODUCTION OF 2-SUBSTITUTED 4-HYDROXY-4-METHYLTETRAHYDROPYRANS HAVING STABLE ODORIFEROUS QUALITY |
| 摘要 |
The present invention relates to a method for the production of 2-substituted 4-hydroxy-4-methyltetrahydropyrans from the acid-catalyzed reaction of 3-methylbut-3-ene-1-ol with an aldehyde, a stable odoriferous quality being achieved and avoiding off-odors that interfere with the odor sensation. |
