摘要
研究了利用红外光谱法、Ｘ射线衍射法表征纤维素与ＮａＯＨ水溶液作用规律。结果表明：纤维素随作用碱浓度增加，作用时间延长能形成络合物；纤维素在低浓度碱中较稳定。红外光谱的纤维素特征吸收峰１３７５。
Interaction rules between cellulose and NaOH solution were studied with IR spectrum and XRD methed. The results indicate that cellulose can make up complex with increasing density of acting alkali and lengthening time; cellulose is more steaty in low density alkali. We decribed quantatively the content of cellulose Ⅱ in the interaction process of cellulose and alkli by means of the relative absorptive strength ratio of sensive absorptive peaks (IR), 1 375 cm -1 and 1 325 cm -1 and X-ray diffracting pattern. The studied conclusion has actual meaning to making paper, man-made board and timber industry.
