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.
本发明涉及一种由 3-甲基丁-3-烯-1-醇与醛在酸催化下反应生成 2-取代的
4-羟基-4-甲基
四氢吡喃的方法,该方法既能获得稳定的发臭质量,又能避免干扰气味感觉的异味。
