DETERMINING OF FUNCTIONAL GROUPS LOCALIZATION IN β-CYCLODEXTRIN NITRATES

Abstract

An IR spectroscopy-based method was devised for estimating the degree of substitution of hydroxyl groups with nitrate groups into the positions 2, 3 and 6 of the glucopyranose ring individually in cyclodextrin partial nitrates. Gauge dependencies as well as the values of molar extinction coefficient were obtained for groups in each position. Primary sources of errors affecting the accuracy of determining the localization of functional groups in β-cyclodextrin were analyzed. Relative error of the evaluation of the number of nitrate groups in positions 2 and 3 of cyclodextrin glucopyranose ring is 10 % and 20 % for position 6.
