cotton cellulose was treated with 1 and 3 m sodium hydroxide at 170-190 $degree$ c under oxygen pressure of 200 and 400 kpa. about 60-70 percent of the cellulose was converted into low molecular weight carboxyli acids, which were analyzed by capillary gas-liquid chromatography-mass spectrometry. in all, 60 acids were identified, of which formic, glycolic, lactic, oxalic, 2,3,4-trideoxyhexaric and 3,4-dideoxyhexaric acids were the main compounds. several c//7-c//1//0 hydroxy dicarboxylic acids were also detected, but these remained mainly unidentified.
