Abstract
Gas chromatography of the mixtures of various O-methyl- and O-ethylglucoses prepared from partially O-methylated and O-ethylated celluloses by acid hydrolysis respectively, was carried out on OV-7 column by the linear temperature-programmed method after the mixtures being converted to O-acetylated aldononitriles.
The Kováts retention indices were determined for each component in the mixtures and the correlation between the chemical structures and the retention indices of O-acetylated aldononitriles of various O-methyl- and O-ethylglucoses was discussed comparing with the case of the corresponding O-acetylated alditols described in the previous papers. It was concluded that the gas chromatographic retention behaviour of O-acetylated aldononitriles was similar to that of O-acetylated alditols except a few points.
