PARTIALLY METHYLATED CYCLODEXTRINS AND PROCESS FOR PRODUCING THE SAME

摘要

This invention relates to partially methylated cyclodextrins with enhanced solubility in water wherein the average degree of methylation at hydroxyl groups of different positions in all the glucose units involved is at least 90% for 2-position, 25 to 35% for 3-position, and at least 95% for 6-position, when measured by 13C-NMR analysis, and to a process for producing the same.
