| Description |
Modification of hydroxyl groups of beta-cyclodextrin (beta-CD) and its n-heptane at 50 C has been carried out with acetic, propionic, butyric, isobutyric, valeric, isovaleric, lauric, octanoic, palmitic and stearic acids. Degree of modification is determined from 1H NMR. Although the ratio of beta-CD to organic acid employed is 1:50, 6.8 OH groups on an average are found to be modified with acetic acid, 0.38 with propionic acid and 2.43 with isobutyric acid. Heptakis-2,6-di-)-methyl-beta-cyclodextrin (DMbeta-CD) and hydroxypropyl-beta-cyclodextrin (HPbeta-CD) which are already substituted with methyl and hydroxypropyl groups, respectively show degrees of substitution to be 2.45 and 2.0 at the freely available 2-OH or 3-OH hydroxyl groups.
