Process for preparing heptakis-(2,6-di-O-methyl)-beta cyclodextrin

摘要

the invention concerns a method for the production of heptakis [2.6.- di - o - methyl] - beta cyclodextrin by methylieren of beta cyclodextrin in organic phasealthough beta cyclodextrin in the presence of alkalihydroxid with dimethylsulfat at temperatures of - 10 to 0 c is methylated.
