Abstract
A method for separating and purifying branched beta-cyclodextrins from aqueous solution. The process entails adding a beta-cyclodextrin complexant to a starting solution, recovering the precipitate so formed, dissolving the resulting precipitate in water, adding a second dose of beta-cyclodextrin complexant to the solution and recovering branched beta-cyclodextrin from the resulting liquor.
