Abstract
A mixture of alpha‐, beta‐, and gamma‐cyclodextrins is cross‐linked with epichlorhydrin in alkali, giving a stable resin with glyceryl bridges between the cyclodextrin units. The resin forms specific inclusion complexes with many compounds. Isotherms of this process have been determined in aqueous solutions with benzaldehyde, aniline, p‐ and o‐nitrophenol, pyridine, butyric acid, iodine in potassium iodide, Congo red, methylorange, and methylene blue. For comparison isotherms have also been determined with the same substances for a commercial cross‐linked dextran without inclusion properties. The data illustrate a considerable ability of the cyclodextrin resin to form inclusion compounds.Keywords
