大麻秆浆制备醋酸纤维素的研究
Study on Reaction of Preparing Cellulose Acetate from Hempen Pulp
摘要
Abstract
Cellulose acetate was prepared from hempen pulp and acetic anhydride. Effects of sulfuric acid amount, temperature, reaction time, acetic anhydride and glacial acetic acid amount on degree of substitution （DS） and degree of polymerization （DP） of cellulose acetate were studied, and cellulose acetate was characterized by infrared spectroscopy （IR） and X-ray diffraction （XRD）. Results showed that DS was increased with sulfuric acid amount, temperature and reaction time, and DP was reduced accordingly. DS was increased with acetic anhydride, and DP was increased with glacial acetic acid amount. The suitable condition of preparing cellulose acetate was determined as follow： 0.13 sulfuric acid, 9.0 acetic anhydride, 9.0 glacial acetic acid （mass ratio to hemp pulp）, 50℃, and 1 h time. In the condition, DS was 2.92, and DP was 121. Acetylation of hempen pulp was confirmed by IR and XRD.关键词
