Crystalline cellulose I and amorphous cellulose II were nitrated with H2SO4 and HNO3 to produce the various nitrates which are different in the fine structure and the amounts of nitro groups. When they were treated with NO2, the behaviors of the functional groups of the products were followed by an infrared spectroscopy.<br>1) The nitrate ester of amorphous cellulose II was more nitrated and oxidized with NO2 than the nitrate ester of crystalline cellulose I.<br>2) The amount of COOH group was increased with the time of reaction, although the degree of substitution was either great or small.<br>3) When the degree of substitution of the nitrate was 1.0_??_1.5, the amount of the nitro group was not changed by NO2-reaction, but it was increased or decreased up to about 8.6_??_9.0N% eventually, when the degree of substitution was smaller or greater than 1.0_??_1.5, respectively. The OH group which was party denitrated by NO2-reaction appeared to be oxidized to COOH group.
