Title:
METHOD FOR PRODUCING 2-ADAMANTANOL AND 2-ADAMANTANONE
Document Type and Number:
WIPO Patent Application WO/2006/006413
Kind Code:
A1
Abstract:
Disclosed is a method for producing 2-adamantanol and 2-adamantanone from 1-adamantanol wherein at least one acid catalyst selected from Lewis acids and solid acids is used as a catalyst in combination with at least one selected from the group consisting of carboxylic acids, sulfonic acids and phosphoric acids. By this method, 2-adamantanol and 2-adamantanone can be selectively and efficiently produced without using sulfuric acid as a catalyst. This method is suitable for mass production since labor for processing a waste acid is saved and reaction time is significantly reduced.
